Tsentr. n. -i. in-t chernoy metallurgii, 1956, Nr 15, pp 53-67 ABSTRACT- Resistance (R) measurements and dilatometric investigations were employed to determine the effect of heat treatment and work hardening on the properties of Fe-.Ni-Mo alloys of constant Ni contents (about 80%) and various Mo con-tents (0-6%), also the kinetics of structural transformations in alloys. The R of a hard- ened specimen of Ni3Fe alloy (0% Mo) after heating and slow cooling in the temperature interval of order/disorder transition declines by 17.5% due to ordering. Addition of up to 1% Mo dim- inishes this effect, and when more than 1% is added, its sign is reversed. In an alloy with 5% Mo, the increase in R attains 5%. On work-hardening, contrariwise, the R of alloys with 5-6% Mo diminishes by 13%, and the R of the ordered Ni3Fe alloy (OA) Ca rd 1/2 increases by 36%. Dilatometric investigation of isothermic 137-58-4-8094 The Effect of Molybdenum on Order/Disorder Transitions in Permalloy tempering of a@hardened specimen'of Ni3Fe shows the reduction in volume common in OA. Under the same conditions of tempering, an alloy having 5% Mo showed the opposite, viz. , an increase in volume. In cold-drawn speci- mens of Ni3Fe.. quenched from 300-6000C, the R drops rapidly with time un- til equilibrium is attained. In Fe-Ni-Mo alloys, R increases in the same man- ner at all tempering temperatures. The greatest change in R in both cases is that occurring at 400-5000. Heat treatment in the 300-6000 interval does not affect the microstructure of the alloy. The anomalous change in the proper- ties of Fe-Ni alloys when > 1% Mo is added is explained by the appearance of a K phase which may perhaps owe -l.ts existence to the fact that the Mo and Fe atoms form complexes as a result of the appearance of chemical bonding forces between the different atoms. These complexes are the reason for the supplementary scattering of electrons and consequently the increase in R. An alloy containing 1% Mo is midway between OA and alloys with a K phase. 1.

In super-cooling the 61 phase of alloys containing 4 - 10 percent V, as well as during isothermal exposure of these alloys, the decomposition process also occurs by diffusion; how- ever, when alloys containing 6 - 10 percent V are cooled at a rate of 5 - 6 deg/min the process of the t -C< T assumes a non-diffusive martensite character. At identical cooling rates the N T in a 4 percent V alloy is of intermediate nature, but la_nges to a martensite nature when the cooling rate is in- creased. From the results obtained it is concluded that both the kinetics and the mechanism of T in a super-cooled gamma phase of the' alloys investigated may be interpreted by means of the usual theory of decomposition and martensitic transformation.

Ti and Nb increase the coercive force of Ni-Al-Fe alloys up to 550 Oe with a B,X5000 gauss (Nb) and 380 Oe at 6350 oauss (Ti). These alloys may be machined by hard alloy cutters.

Vol 2. Moscow, AN SSSR, 1957, pp 171-180 ABSTRACIC: The fact that electrical resistivity (ER), heat capacity (HC), and certain other properties of nimonic and nichrome alloys are functions of temperature indicates that a K-state exists in these alloys. In nichrome specimens which have been quench-hardened at a temperature of 7700C, the K-5tate appears as a result of heating to 400-460c@ Heating the alloy to 460-5600 causes it to revert into a statically disordered solid-solution state. The formation of the K-state is accompanied by changes in the micr05tructure of the alloys, apparently as a result of deformations,, i. e. , according to X-ray data the alloys retain their single-phase character. Card 1/2 A change in microhardness analogous to a change in the ER SOV/1 37-58-10-21512 Theory of Phase Transformations in Nichrome and Nimonic is observed. In the case of nimonic two processes take place: 1) Segregation of a Ni3(Ti, Al) phase from the solid solution at temperatu-res of 850-7500, and 2) the appearance of a K-state at temperatures below 500-600c). Despite the high magnifications employed (l 0- 12, 000 x), ele ctr on- microscope 301dies of the structure of nimonic which had been tempered at 500-6000 failed to reveal any decomposition of the solid solution, even though the physical properties of the alloy had changed considerably in the process. The K-state was also studied by the method of measuring the internal friction of alloys with the aid of a vacuum relaxator. On the strength of these data it may be concluded that Ni and Cr participate in the formation of the K-state in nichrome, whereas in the case of nimonic Ni,-Cr,'Ti, and Al are the partici- pating elements. 1.

At these temperatures the decomposition takes place In two Btepst Fe-phase and Ni-Al-phase. The first decomposition is proved with the help of a microscope, the additional one by a phase analysis (chemical and X-ray) of tbfj iso- lated Ni-AIL-phase) which is separated from the alloy alGetrochemically after different heat treatments. The decomposition is also proved by measurements of electrical, magnetical and other properties of the monolyt samples. It can be assumed, that the maximum increase of the coercitive force is caused by an increased Isolation of particles of ck,- iron on the additional decomposition of the phases (which have been obtained at the first decomposition of the undercooled solid solution).

The purpose of this paper was to clarify the influence of Mo on the ordering process of the Ni Mn s@olution. Alloys of Ni Yn nithout nrox lybdenium@ and such with a Aolybdenum content up, to i7fo were i=esti- gated. First the kinetics of the phase transformation at various tem- peratures were studied by means of meawaring the electric resistance, and then this process was analyzed exactly with the thermomagnetic method in the anisometer of Akulove Moreover3 the elastic properties and the structure of the alloys was investigated* It appeared, that the various stages of ordering are accompanied by a process of forma- tiom and growth of the crystal- nuclei*of the ordered solution and a gradual.disappearance of the disordered phase, The introductiom of molybdenum into NiMn slows. down the ordering and diminishes the degree Card 1/2- of the possible ordering. This decrease is not proportional to the Note on Magnetic Investigations of the Ordering of Alloys on the 48.9-5/26 Basis. of Ni-lin. dilution of Ni.,Mn bymolybdenum. The decrease of the extreme order appaxently is tot onV due to a distortion of the stoechiometrical composition, but also to a basic modification of the interatomic combination, The ability of the solid solution for ordering is kept at an introduction of at least 4,1, %of molybdenum and no transition to the inhomogenuous; solid solution, takes place (K - state)& The kinetics of the ordering of Ni-Mn compounds are identical. wether al- 3-- loyed with mol_vbdenunL or not, The baslic contenta of the lerture have been published together@with Myuller, N& N, and Savostlyanova. in. mi 3, 477 (1-956).

TITLE: Investigation of Structural Transformations and Properties of Nichrome Alloys(Issledovaniye strukturnykh prevrashcheniy i svoystv nikhromovykh splavov) PERIODICAL: Sb. Mosk. in-t stali, 1957, Vol 36, pp 75-102 ABSTRACT: The nature and mechanism of the K-state was studied on alloys Kh2ON80 and Khl5N60, which were obtained industrially in the form of a'wire 3.5 mm in diameter. Specimens encased in ampoules containing Na to ensure an oxygen-free atmosphere .were maintained for 5 hours in a silit-resistor furnace at a temperature of lZ000C, after which they were cooled to 11000 within one hour, maintained at that temperature for one hour, and then were either quenched in water or allowed to cool at a specified rate. At temperatures below 4000 the heat treatment was performed in sealed Cu cartridges. At higher temperatures the samples were maintained either in a Sn bath, or in quartz ampoules. Temperatures were measured by means of a Pt-Pt-Rh Card 1/2 thermocouple. In order to study the effect of deformation on the 137-58-3-5865 Investigation of Structural Transformations (cont. ) properties of alloys,, the specimens were subjected to reduction amounting to 98 percent. The effect of vari ous heat treatment procedures and of cold deformation on the properties of alloys, as well as the kinetics of trans- formation, were studied by means of measuring microhardness and electrical resistivity; the latter was measured by a null method on a potentiometer bridge. In addition, the Ob and Is were measured and rr@ic rostructural analysis and dilatometric studies were performed on a Chevenard dilatometer under con- ditions of continuous heati-ig and cooling. It is shown that common aging with carbide separation occurs in the alloys investigated together with intraphase transformations in which no separation occurs and which are accompanied by changes inniicros1ruc'ture, increases in microhardness and in electrical resistivity, and decreases in the permanent solid-solution lattice. In the case of the KhZON60 alloy, both these processes are separated. Activation energies of the intraphase transformation process were calculated from changes in electrical resistivity, and were found to be 43, 300 cal/g-atom for the KhZON80 alloy, and 66, 800 cal/g-atom for the Khl5N60 alloy. If the Kh2ON80 alloy con- tains 0.07 percent of C, the activation energy increases to a value of 55,600 cal/g-atom. It is postulated that regions enriched with Cr are formed wi ,thin the lattice of the solid solution as a result of the intrdphase transformations. V.R.

Electric resistance was measured on "UPN3/2" and "UTV-2" machines during the heating process and at room temperatures; measurements were made on a capacity dilatometer; the temperature dependence of heat capacity was determined by the Sykes (Sayks) method; the phase composition of electro- lytically separated deposits was determined by the roentgenographical, microscopical and electron-microscopical methods. Moreover, endurance tests were performed. Heat treatment of specimens consisted of quench- Card 1/2 hardening with subsequent controlled cooling-off at various rates. Higriest 69181 SOV'/137-59-12-27205 Investigation Into Phase and Structure Transformations of "E1437" Alloy hardness values were obtained if the cooling rate was 160 degrees/hour, corresponding to a sufficiently complete isolation of the separating phases and to not too excessive a coagulation. The electron-midrosnopical investigations showed that the separation and coagulation of the strengthening @11-phase was more intensive during continuous cooling-off from high temperatures than during tempering of a supercooled solution; the particle dimensions depended on the cooling rate. In slow cooling a hexagonal phase was revealed together with the -C '-phase. Measurement of the temperature dependence of specific heat capacity and measurements of electric resistance and dilatometrical data, showed that two processes took place: namely, within the 700 - 90016C temperature range, a process connected with the formation of a phase in the solid solution, and a process of developing a K-state below 700OC; whose thermal effect was equal to 1.35 cal/g. The first process shifted the maximum of the K-state formation slightly towards the lower temperature side. It Is assumed that the origination of the K-state is due to the formation of Guinier-Preston type zones in areas with increased concen- tration of alloying elements; it is characterized by the occurrence of a specific micro-relief.

Upon aging in a low temperature range (300 - 6000) the electrical resistivity and hardness increase, while the saturation magnetization decreases, which indicates the appearance of a K-state. In the high temperature range the changes of the properties exhibit a reverse character indicating an aging process accompanied by the separation of a second phase, which fact is verified by metallographic analysis. The activation energy of the low-temperature process is - 40, 000 cal/g-atom, that of the high- temperature process is - 71, 000 cal/g-atom, i. e. , both are diffusion processes - The Card 1/2 authors also examined the phenomenon of the recovery of properties The K-state and the Phenomenon of Recovery Upon Aging SOV/137-59-1-1097 after aging with a short (5-sec) heating to 7000.

It is only in the alloys with 36 - 37 % that a smaller quantity of the c'-phase occurs. The experiments showed that the 6'-phase in the system Co-Cr directly forms from the liquid me3t.

A maximum is observed at 400-5000 on the hardness, elastic limit, and electric resistance curves of cold-worked alloys of the K40NKhM type as functions of the annealing temperature. The electric resistance curve of the alloys has a maximum also after hardening with annealing. The chief results of the examination of kinetics of the annealing process are given. The occurrence of maxima on the Card 1/3 kinetic curves points to proceases in the alloy that - at Kinvtics and Mechanism of Structural Change SOV/163-58-4-28/47 in Annealing a Cold-Ifforked Alloy of the K40XKhM-Type isothermal retardation - are opposite as to their influence on properties. In the opinion of the authors, the formation of the K-stata leads to an increase of hardness. The electric resistance increases due to a reduction of mobility of the electrons (Refs 6,, 7). The forming zones have dimensions in the order of magnitude of the free path of electrons, increasing thoir straying. A partial softening of the alloy at isothermal retardation is connected with the course of the recovery process after cold hardening. This is confirmed by the dilatomettric curves at isothermal retardation, and by the curves of the actual elongation factor and relative elongation. It is shown that in a hardened (not cold hardened) alloy with the structure of a more or less homogenous solid solution only one process takes place in heating (formation of the K-state occurs up to 5500, and a gradual destruction of the same at a temperature between 550 and 6500). The second process (the recovery) is missing. It is shown that cold hardening greatly reduces the elastic modulus (in the given caso by 20 %), and therefore the Card 2/3 interatomic binding powern too. Subsequent annealing at Xirzetics and Mechanism of Structural Change SOV/163-58-4-28/47 in Annealing a Cold-'forked Alloy of the K40NKhM-Type different temperatures (for 4 hours) increases the elastic modulus. This is connected with the formation of the zone of Ginlye-Preston's type (K-state). There are 5 figures and 11 references, 4 of which are Soviet.

The examined alloys are listed in the table. The information collected permits to draw the following oonclusionst In the hardened solid alloy the molybdenum atoms are in the free state. For this reason under the influence of the external strains a co- ordination takes place without hindrance, iee. a new orienta- tion of the atom-pairs of molybdenum (according to the model Card 1/3 by Siner). When the alloy is worked unto the K-state, zones Modification of Structural Transformations inBa%,.YZ2.uy SOV/48-22-10-19/23 DOXIM A33b7IM With Molybdenum (of the type of the Guinet (Ginlye) - Preston zones) containing the molybdenum atoms are formed. The alloy beh.ves as if an intraphaae saparation had taken place in it. The molybdenum atoms in this case are no longer in the free state and therefore cannot participate in the ooordina- tion under the action of a strain. Therefore the maximum of the internal friction initially decreases and in the case of a protracted tempering completely disappears. The measure- ments of the internal friction showed that the molybdenum atoms in the case of the formation of the K-state apparently are removed from the solid solution. This fact proves that in solid solutions during the process of tempering zones are forming which contain the molybdenum atoms and which in their composition differ from the basic solid solution. The investigation of the temperature dependence of Young's modulus in Fe-Ki-No alloys shoft that this modulus increases when the K-state forms.

Metallurgiyat 1959, Nr 1, Pp 17o - 174 (USSR) ABSTRACT: The investiCation of the non-mag ,,netic corrosion resistant s-ring alloy N36KhT (Ref 1) showed that after hardrning at temperatures above 9000 an oversaturated solid solution was forined. A consolidation occurs if the alloy is aged afterwards. The consolidating phase is the intermediate phase of the (11i,Fe) Ti-type -,-rith a heNaoonal lattice. The electric resistance 9f the alloy increases in the initial ctaje of a6ing at 4CO-6000, and decreases at higher temper- atures. This anomalous phenomenon has for th.-. -rir.,;t time been discovered in Al-Cu alloys (Ref 2).

The metallographic analysis sho-wred tlat the consolidating phase separates only at 5COO and above. Hence it appears that during aginE, two processes occur in the - alloy N36KhT, which, howevcr, cannot clearly be distinguished in the temperature citrve. In order to determine the nature of the process at lo-,,,er tem@@eraturos the influence cf cold working upon the proporties of the samrles -aas investiLatcd. The rehabilitation ghenomena were invcstizated after aging at 400, 450 and 500 . This effect was also ascertained with the help of a dilatometer. The investiZ:ations allow to ma"ite the following statements: The aging process in the alloy N36KhT proceeds in two stalres. At 400-500 0 it is primarily that of a formation of the K-state, whereas at ter.1-craLures above 500 0 the (Ili, Fe) Ti-phase is primarily separated. The increase of the hardaese and of @he electric resistance by aging at 550-5500 is basically due to the K-state. This Card 2 structural state is removed by cold workinC. An at;ing at 5000 Rehabilitation Phenomena After Aging in the Alloy N36KhT SOV/1634-519-1-33/5o after cold working leads to a rehabilitation of this ztate. The anomalous rise of the electric resistance due to aging at low temperatures is apparently a reoult of an independent process (the formation of the x-state) and not a result of the preparation for the separation of the second phase. The incomplete rehabilitation of properties indicates that by a short-term heating to high temperatures the K-state is destroyed, whereas the separations of the second phase are stable. A comparison of the results obtained in this work with earlier results (Ref 6) shows that in 1136KhT the same processes occur during aging as in Invar steel alloyed with niobium. A comparison of the aging process in alloys of the Fe-Mo-, Fe-W-, and Fe-M-11b systems (Rei's 6,7) with that of N36KhT indicates that the rehabilitation of properties is found in such alloys, in which an anomalous modifica- tion of properties (primarily of the elect:.-ic resistance) occur in the intial stage of aging, which is connected with the formation of the K-state.

Metallurgiya, 1959, Nr 1, pp 174-178 (USSR) ABSTRACT: The drawing of cold-worked spring alloys of the type K40NKhM at 400-5000 lei@ds to an increase in hardness, to a rise of the proportional limit, of the electric resistance and of Young's modulus. In other papers (Refs 1, 2) the authors voiced the opinion that by drawing the temper of these alloys a K-state results. This state is characterized by the existence of segregates of homogeneous atoms of the Gi.-alye-Preston zone type. By using the dilatometric method it was demonstrated that in drawing cold-worked alloys of the K40NKhM type two processes are released. They result in a reduction of the volume and of the strain coefficient. From the information gained by measurements of internal friction (Ref 1) it was assumed that Card 1/3 the K-state in alloys of a K40NKhM type consists in the Mechanism of Structural Transformations Occurring SOV/163-59-1-34/50 During the Drawing of Cold-worked Alloys of the type K40NKhM formation of segregations of molybdenum end tungsten atoms. Two alloys were investigateds the Co-Cr-NI.-Fe basis of the K40NKhM alloy, and the same basis, to which molybdenum was alloyed additionally. The investigation showel that an addition of molybdenum facilitates the formation of a K-state in the alloy, and that in this process also other atoms (probably chromium) participate. A similar influence is also exerted by molybdenum upon the elastic limit of the alloys. After drawing at 5000 the elastic limit of a molybdenum alloy increases from 110 to 160 kg/mm2. If the drawing temperature is increased the elastic limit is reduced. The data collected demonstrate that the high elastic limit of such an alloy is due to the molybdenum (and tungsten) content of the solid solution. An increase of the electric resistance, whiph is typical of the K-state, was found in the molybdenum alloy. In the alloy containing no molybdenum no anomalous increase of the electric resistance was found. In conclusion it is said that the Card 2/3 improvement of the elastic properties cezi mainly be ascribed to 'Mechanism of Structural Transformations Occurring SOVI 6 3- 5 9-1 - 34/5 0 During the Drawing of Cold-worked Alloys of the Type K40NKhM the presence of molybdenum in the alloy and that the carbon constituent plays only a minor part in the increase of Young's modulus and of the electric resistance due to drawing.

The samples were hardened and then tempered at different temperatures and stored for aging. The dependence of the properties of the Fe-Mo (21% Mo)- and Fe-W alloys (16*, W) on the tempering temperature was investigated and the re- sults are given in figure 1. The kine@ic aging curves in the Fe-Mo alloys (12% Me) show at 600 that the aging process proceeds in three stages; spontaneous decomposition in the case of an aging duration of 30 minutes; colloidal equilibrium after an aging of 1 - 10 hours and coalescence after an aging duration of more than 10 hours. The change of the proBertiee in Fe-Mo alloys in the cafie of heating below Card 1/2 400 is given in figure 4. The alloy of the system Fe-W (16@.

The aging in the alloys Fe-Mo and Fe-W has the same character. The change in the properties of the alloys of the two systems is connected with the oc- currence of a second phase.

Borodkina, Makhukov and Sollts have shown (Ref 1 and 2) that the alloy, as quenched from a temperature of 1100 to 1150*C' possesses a one-phase structure with a face-centred cubic lattice. On cold working by rollin f or wire-drawing, followed by tempering at 400 to 500 C, the alloy acquires high elastic properties, strength and hardness. Fig I shows the change in hardness, elastic limit and electrical resistance of a K40NXhM alloy, containing 0.050% C, on tempering (soaking for 2 to 4 hours) after a 70% cold deformation. The authors of this paper undertook an investigation of this alloy with the aim of establishing the mechanism of hardening during tempering.

B - 0-015Y9. (State of the alloys before tempering: 1 - deformed 70%, 2 - deformed 30%, 3 - water quenched from 11000C.) The authors arrive at the following conclusions; 1. Two independent processes take place during tempering in cold worked K40NKhh' type alloys. One of them occurs preferentially in the temperature range 300 to-350*C and probably leads to the formation of atomic segregations of the C,,uinier-Preston zone type (K-state). The second process occurs preferentially in the temperature range 550 to 7000C and leads to the precipitation of a second phase from the solid solution as well as to an acceleration of relaxation and recrystallization. 2. The low temperature process is accompanied by increase in hardness, elastic limit, modulus of elasticity and electric resistance and by a decrease in volume and the true coefficient of expansion of the alloy. 3. In a homogeneous solid solution (after Card 3/4 deformation) of alloys of the K40NKh]4 type, containing sov/126-8-3-12/33 Investigation of the Tempering Process of the Cold Deformed Alloy PAONKhM atoms of metallic components of different diameter and carbon atoms, a peak appears on the curve Q-1(T) for Internal friction at 300 to 350*C. This peak is due to the relative displacement of carbon atoms and atoms of large atomic diameter (Mo, W). 4. The magnitude of the 3.nternal friction peak increases with increase in carbon concentration and degree of deformation. 5. The segregation of Mo and W atoms is the reason for the decrease in the magnitude of the internal friction peak on tempering after cold working. This enables the process of the K-state formation to be studied by the internal friction method. In such an investigation C serves as an indicator for the formation of segregation of the constituent metal atoms.

TITLE: Internal Friction of Metastable Solid Solutions PERIODICALiFizika metallov I metallovedeniye, 1959, Vol 8, Nr 3, pp--440-448 (USSR) ABSTRACT: The alloy of stoichiometric composition Ni 3Mn and alloys of the same composition alloyed with 1.34 and 2-77% Mo, respectively, were studied by measuring the temperature dependence of internal friction. Using this method, Ni 3Fe type alloys without molybdenum and those alloyed with molybdenum, And also E1437A type alloys (nimonic) were studied. The chemical composition of the investigated alloys Is shown in the table on p 441. The internal friction was measured in wire specimens, 300 mm long and 0-7 mm diameter, in vacuum. The alloy N'3Mn is an ordered alloy with a Curie point of approximately 350% (Ref 10 and 11). In the curve showing the temperature dependence of internal friction of a quenched Ni Mn alloy (quenched from a temperature above that at whi2 orderin f occurs) two peaks, A and B, with maxima at 120 and 290 G are I/ Card 1/4 observed (Fig 1). In the curve of the temperature VK 66234 Internal Friction of Metastable Solid Solution !OV/126-8-3-ib/33 dependence*of internal friction of a deformed N'3mn alloY (75% deformation)* the peaks A and B remain and an additional peak, D, having a maximum at 220C, appearal the general level of internal friction rises sharply (Fig 2). An additional peak, C, having a maximum at 3!6*C, is evident in a carburiz d Ni@Mn alloy containing 0-35% C (Fig 3). The appearanc: of his peak is due to the diffusion of carbon atoms in the elastic stress range. During the investigation of the influence of alloying the Ni3Xn solid solution with molybdenum, it was found that supplementary maxima - peaks M and C at 52 and 3160C - appeared in temperature dependence of internal friction curves (Fig 4). In Fig 5, the influence of heat treatment on the temperature dependence of a N'3Mn alloy containing 1.34% No is shown. A similar result is obtained with an alloy containing 2.77% Mo- On measuring the internal friction of N'3Fe alloys alloyed with Mo .(Fig 6) two peaks were obtained in the low temperature range;, one in the region of 85*C (peak A) and the other at 17 C (peak B).

In Fig 9, the change in internal friction with Ti content in a nimonic alloy is shown. The authors conclude that on measuring the temperature dependence of internal friction of metastable solid solutions characteristic effects can be expected even when the structural factor is exceedingly small. The magnitude of the effects in this case must be the greater, the greater the difference in free energy between a quenched and tempered alloy. A comparison of the internal friction of ordering alloys with that of alloys forming a K-state structure at lo-i- temperatures is exceedingly interesting (see Fig 4 and 6). On adding molybdenum to ordering alloys (N13Mn) the metastability peak decreases as molybdenum decreases the degree of possible order. Conversely on adding this elementto K-state alloys (Ni3Fe + Mo) the metastability peak increases, as the increase in molybdenum concentration appears to increase the extent of atom segregation (K-state) in the solution. Card 3/4 The same can be said about titanium in the alloy E1437 66234 SOV/126-8-3-18/33 Internal Friction of Metastable Solid Solutions (Fig 9).
