The object of the present investigation was to study the simultaneous effect of two horophili,.* additior-s. The experimental alloys whose detailed chemical analysis is given in a tabile on p 633, contained 6% Ag with 0.2 - 0.5% Sb and. 0.02 - 0.3% Be added either separately or jointly. The alloys*were melted in a H.F. induction furnace,'in a graphite crucible with borax used as the co-wering flux. The. cast ingots were heated under charcoal to 8000C, held at the temperature for 2 hrs and cooled in the furnace. They were then rolled to strip 5 mm thick which, after a homogenising tx-eatment consisting of 50 hours at 8000C was used for the preparation of the experimental test pieces. The pxo-less of ageing was studied by measliming the -variation of hardness, magnetic susceptibility and electrical resistance.

Mavaetic susceptibility was measured with the aid of a magnetic balance at room temperature and at 370, 400 and 4200C. The measurements were taken at 10-15 minute interv la and in every case the value of relative magnetic susceptibility was determined, i.e. the force actin on the in:vestigated specimen was comparecl with the force acting on a standard nickel sulphate specimen placed in an identical magnetic field. Electrical resistance was measured by the comparison of potential drop method, using a poteatiometer and a sensitive galvanometer. .In this case, both the solution treatment and ageing (at 3700C) were carried out in vacuum and the measurements wezv taken at 15 minute intery ls.

The following interpretation of the obtained results is offered by the present authors: The average rute, Ye of the isothermal decomposition of a super- saKrated solid solution of silver in copper is markedly affected by small s3"IMIltauisously present additions of Sb and Be. even when these elements are present in concentrations considerably lower than their respective solid solubility limits. When added separately, antimony accelerates and beryllium slows down the process of decomposition. Howevwrs these effects are not additive when Sb and Be are present aiiaLitaneously: At a given Sb concentration vem increases at first with the increasing Be content, reaches a maximum and then slowly decreases (Fig-1-3), The higher the content of antimony the higher are the Card 7/11 values of v., for any given beryllium concontrations SOV112ra-6 - 4--'9/34 The Effect of Small AddLitions of Antimony and Beryllium or.

The basic, difficulty in studying phase transformations in f austenitic steels is the fact that the uantity and dimensions of the rejected phase are very small and annot be detected by X-ray i. c metallographic and other methods (Refs. 1 and 2). In view of the pronounced differences in the.magnetic properties of the para- magnetic base, the carbides and the ferromagnetic a-phase, preference should undoubtedly be given to magnetic metallography and thormomagnetic analysis, i.e. to the study of the magnetic susceptibility, its dependence on the magnetic field potential and 1/,7 S/520/59/000/022/011/021 E073/E535 On the Influence of Hot Forming on the Magnetic Properties of Austenitic Steel the temperature. The author has investigated the susceptibility of two grades of austenitic. manganese steel...-Dotermination of the magnetic susceptibility reduces to measur"ng the mechanical force acting on a specimen which is placed into a non-uniform magnetic field. The apparatus for measuring the magnetic susceptibility consists essentially of magnetic scales as described by V. I. Drozhzhina and R. I. Yanus (ZhETF, 1936, 6, -N'o-3,i25O). A ..specially selected shape of the pole-shoes of the electr'omagnet enable obtaining a highly nonuniform magnetic field in 'the x- direction. The current in the electromagnet was vari6d between 0 and 8 A corresponding to a field potential between d and 4200 Oe. The force acting on the specimen when placed between the poles of the electromagnet was balanced by a pulling or pushing"-force from the compensating coil of the permanent magnet. The balancing forc*e: was proportional to the current flowing through the compensation coil at the instant of compensation. In this case the follo*ing relation is valid Card 2/7.

After deformation at room temperature, the susceptibility changed only slightly (within the range of measuring errors). Equally, deformation at the temperatures 500, .1000 and 1100% did not produce any appreciable change ~n the ~susceptibility. The temperature dependence of the maghetic susceptibility of this steel (after 22% reduction) is plotted in Fig.!

The stability of the austen- is attributed to tha chemical composition of this steel (0.58 to. '0 .71% C, 8% NI).

The considerable increase in susceptibility during cold working indicates austenite decomposition with rejection of a ferromagnetic a-phase.

At deformation temperatures above 2000C austenite does not decompose.-The slight increase in the magnetic susceptibility in the temperature range 550 to 600*C can be attributed to processes of ageing, which are accompanied by rejection of carbides and also of the a-phase. The sharp change in the mechanical characteristics (a ,, a.),observed in some cases for slight changes in the deformatio telperature (200 to 2200C) are apparently due to the appearance of.a*ferro- magnetic a-phase owing to the influence of the deformation at these'. temperatures.

TITLE-. InFluence of Deformation of Martensite on the Cold Shortness of Austenitic Steels and Their Hardening in Plastic Deformitiont- PERIODICAL- Fizika metallov i metallovedeniye, i.96o,, No. 1, pp. 122 - 130 TEXT: Investigation of a series of austenitic steelJ has shown that some have a tendency to brittle fracture.11The authors point out that martensite formation during co]A-shortness testing is the-probable cause and that liability of austenitic steels to fcm martensite in plastic deformation depends on the position of the deformation temperature relative to the martens�te point (Rerf 2) and the temperature at which austeni-te and martensite free energies are equal. Their present work dealt with the following steels (analysis in Table 1):\i~LQqjj, 4OG18Kh4, 40G18Khg, 40r.18Kh4N4, 4ornfth4M, 4oGlfth4NV.~I~oGA, 50r.18Kh4, 50G18Kh4N8V, 50G13Kh4N4, covering the composition ranges W: o.4o - 0.55 C. 0-0-71 Si 17-30-18.6o Mn.. o-8.o Cr, 0-8-32 Ni, Card 1/4 1~ 81908 S/126/60/010/01/013/019 Elll/B335 Influence of Deformation of Martensite on the Cold Shortness of Austenitic Steels and Their Hardening in Plastic Deformation 0-0-71 W, 0-0-010 S, 0-0.067 P. 60 mm, long pieces were cut from 12 x forged bars. The pieces were heated to 1150 0C and cooled in water. Magnetometric -tests showed no martensite trans- formation on cooling to -196 OC. Standard notched test-pieces (2 nim deep notch, I mm radius of curvature) were used for impact t;ests from room to liquid-nitrogen temperature. Alpha-phase (deformation martensite) was found with great sensitivity by measuring magnetic susceptibility (Ref 3) of austenite on 3 x 4 x 9 mm pieces cut from the fracture region of impact speci- mens, Mohr's salt being used as the standard. In a second series of experiments the austenitic steels after quenching from 1150 oc were rolled at 20-600 OC to give 30% deformation. Figs. 1-3 show the toughness of the various steels as functions of test temperature, the effect of the various alloying elements being brought out; magnetic susceptibility as functions of test temperature being similarly shown in Figs. 4 and 5. Figs. 6 and 7 show deformation of martenaite structures and Fig. 8 the fractures obtained at various temperatures.

The reason for the cold shortness is deformation-martensite formation during low- temperature impact testing. The good effect of alloying the manganese steels with chromium and nickel is explained by the increased austenite stability with respect to plastic-deformation induced martensite transformation. Formation of such martensites is the reason for the greater hardening of manganese austenitic steels in cold compared with 200-300 OC plastic deformation.

By changing the preliminary heat treatment it is possible to obtain an austenite with various degrees of alloying and various compositions of the secondary phases. Changes in the phase composition during preliminary heat treatment of austenitic steel may bring about changes in its magnetic properties due to formation of 6-ferrite resulting from quenching at elevated temperatures. For this reason, the authors considered it of interest to study the influence of preliminary heat treatment and nitriding on the mechanical properties of austenitic steel. Two steels of the following compositions were investigated: (in %) Card 1/5 S/129/60/ooo/oll/oo4/oi6 E073/E535 Influence of Heat Treatment and Nitriding on the Mechanical Properties of Austenitic Steels Steel .

The steel lKhl8N9T was additionally subjected to "wrong" nitriding: tinned specimens were charged into a furnace simultaneously with the nitrided specimens of the same steel. The magnetic properties of the steel E1123 were determined after normalization annealing or after normalization annealing and ageing. The normalization temperature was 1150 and 1070*C. The preliminary heat treatment of the steel IKhl8N9T consisted in quenching from 1150*C in water and subsequent ageing. Both steels Card 2/5 S/129/60/000/011/oo4/ol6 E073/E535 Influence of Heat Treatment and Nitriding on the Mechanical Properties of Austenitic Steels were aged for 8 hours at 8000C. The specimens were in the form of 12 mm diameter, 5 mm long cylinders. The magnetic susceptibility of the steels E1123 and lKhl8N9T in the paramagnetic state was measured by means of magnetic scales at various field strengths as to determine the 'X(H). For investigating the magnetic propi:rstoies of the nitr�ded steels, specimens in the form of tubes with an* external diameter of 8 mm, a length of 60 mm and a wall thickness of 0.5 mm were used. The external surfacesof the specimens were ground whilst the internal surfaces were machined by means of a reamer. Prior to nitriding, the specimens were etched in a hydrochloric acid solution at 700C for 5 min and then nitrided in a laboratory furnace at 600*C, with a holding time of 65 hours for the steel EI123 and 75 to 55 hours for the steel lKhl8N9T. The 75 hour holding time corresponded to the maximum depth of the nitrided layer for specimens with a wall thickness of 0-5 mm. The magnetic properties of nitrided specimens were measured ballistically in an open magnetic circuit. On the basis of the obtained results, which are given, the following conclusions are arrived at: Card 3/5 S/129/60/000/011/004/Oi6 B073/E535 Influence of Heat Treatment and Nitriding on the Mechanical Properties of Austenitic Steels 1) Changing of the normalization annealing temperature of the steel EI123 from 1070 to 1150*C and additional ageing for 8 hours at 800*C does not bring about a change in the susceptibility of thisztM2. 2) Nitriding changes to a considerable extent the magnetic permeability of the investigated steels; the nitrided layers of both the investigated steels were f erromagnetic and this is due to the formation of nitrides, impoverishment in alloying elements of the austenite and austenite decomposition. 3) As a result of nitriding, the magnetic permeability of the steel Y EII23 increases consid6rably (by a factor of 3) as compared to the steel lKh18NqT. 4) Increase in the depth of nitriding brings about an increase of the maximum magnetic permeability; with increasing relative depth of the nitrided layer of the steel EI123 from 23 to 48.5% the maximum permeability increases by more than double. With increasing relative depth of the nitrided layer of the steel lKhl8N9T from 50 to 93.65%, its maximum permeability increases from 3.7 to 19.8 gauss/0e.

The influence of nitriding on the magnetic properties of steel similar to the previously tested 1 X 18 H 9T (lKhl8N9T) steel but not containing titanium was studied to verify this conclusion. The compositions of the two steels studied were: IKhl8N9: 0.14,/~o' C; 0,66% Si; 0.85% Pln; 17.68Yo Cr; 9.02% Ni, 0.07% Ti; o.ol6% s; m16% P.

The magnetic properties were determined after heat-treatment (quenching from 1150 *C in water, followed by ageing for 8 hours at 800 *C). Both steels were paramagnetic in the quenched state and their susceptibility values were nearly the same. After a7eing the susceptibility increased somewhat, the permeability of b,t,"i steels after quenching and ageing approached unity and did not depend on the field strength. In the nitrided state the max2.mum permeability of the steel without T:L was considerably lower than in the steel with Ti. For a relative depth of the nitrided layer of 57.4% the steel lKhl8N9 had a maximum permeability of 1.8 gauss/0e, whilst for the steel IlChl8N9T the maximum permeability was 3.7 gauss/Oe for a relative depth of the nitrided layer of 50Yo. The structures of the n1trided layers of both steels were identical, consisting of austen:Lte and carbide grains in the heat-treated state; the structure of the nitrided layer was reminiscent of sorbito, due to the partial decomposition of the'a-phase and the carbides during Card 2/4 Magnetic properties of the steel.. S/126/62/013/004/019/022 E073/El35 nitride-formation. The following conclusions are arrived :-,t: Nitriding c1langes considerably the magnetic propertles of steels IKhl8-\'9 and JKh18N9T; the ferromagnetic nature of the nitrided layer is due to the formation of the a-phase during nitriding. The steel lKhl8N9T has a higher permeability in the nitrided state than the steel IKhl8N9, and the difference is attributed to the presence of TI in the former, which forms stable nitrides and impoverishes considerably the y-phase of Ti, reducing its stability and bringing about rejection of OL-phase. The- stability of the austenitic structure after nitriding was determined by the concentration of admixtures required for forming uniform austenite and by the ability of the components entering into the austenIte to form stable nitrides, The nitrided skin of austenitic steel components should have low permeability values.

For the same deformation conditions, a fuller decomposi- ,~ion of austenite occurred in large-grained samples as a result of the variation of ni-~ ,the position of the martensitic point for a change of grain size (the point of the i * Itial martensitic transformation of large-grained -;;xnples was located higher than fine- grained). Under the effect of deformation in the steel, a much greater amount of a- phase formed than during tempering. A definite correlation was found between the na-r ;ture of the magnetic and electrical property changes on the one hand and the mechanical!, properties on the other, as a function of tempering temperature.

Various opticalsystems were used for ,of this signal redw passing the direct,and reverse beams to the photoelectric mixer with a simultaneous reduction in. the,enorjW reflected into the resonator from the external mirrors.' Figures are given sh .owing two . modi fications of systems for reducing the capture band to $Wcps.' Theig of the resonator-wias reduced for a-further reduction of the,band* r i This was doneby replacing one of the opaque mi rors in the resonator wiC-.,_a:se'mi- transparent mirror. The result was a,reduction in the capture band from X-0 to 50 cps at the same output power. The magnitude of the capture band is determined by_~.~ the reverse reflection of enerU from'various elements -in -the resonator' scattering' by, nonhomogeneous media, and , the 'nonlinear depl3ndence. of polarization on the field. -."The aiathors are grateful to-A.
