The heating furnace had two windings and made it possible to raise the temperature to,13500C. The calori- meter, of the mixture type, consisted of a massive copper block housed in a water bath. The error of measurement u- sually did not exceed 0.6%. Data on the heat capacity of 99.2% crystalline Si in the 0- 12830 interval yielded an equation for the relationship of the mol. c of Si temperature: Card 1/3 CP=6.75-1.7xlo-3T+1.3xio-6TZ-I.,37xlo5T-~ 137-58-4-6549 The Specific Heat and Thermal (cont. For engineering calculations, the following formula is handier- CP=5.65+0.8xlO-2'T- 105T-2. The c of lebowite (53.38% Si+ Fe) revealed jumps in c at 300, 650, and 9100, the first two being related to the pre- sence of the lebowite phase.- and the 9100 jump corresponding to phase trans- formation. The c of lebowite is: CPJ=0.1635+21.18~10-6T-2.588T2 at 9100 and Cp =0.1410+52.5xlo-6 for 910-12000. The c of monosilicide (34.48% Si+Fe) is described adequately by the equation: C I-0.131+46.14x,0-6T-250.7 -IT2 for 0-1200'. The c of the Q-phase (Fe3Si2) shows a point of inflection at about 5000, corresponding to magnetic transformation, and a sharp rise in the curve at IOZOO related to the appearance of peritectic decomposition of thenThase. In the 0-5000 interval, HT-HZ73.1=23.7+0.091T+-54.Oxl66T2 - 141 IT- , and at, higher temperatures HT-HZ73. 1=35.75+0.OZIT+70.68x 10-6T2-1277OT-1. Analogous equations are also presented for alloys con- taining 1.04, 1.73, 4.07, ZZ.56, Z8.84, 35.15, 36.42, 44.46, 67.21, 78.49, 86,73, 91.91% Si. The authors have come to the conclusion that, Kopp's law for the Si-Fe system is satisfactorily applicable to alloys high in Si, and practic- ally inapplicable to alloys low in Si.

Equations for the temperature dependence of c were derived for the follow- ing alloys: Cr3Si (15.18% SQ, Cr3Si2 (28.1% Si), CrSi (36.55% Si), SrS;2 (51.05% Si), and alloys of Cr containing 46, 36, 49.66, 62.0, 68.25, and 76.10% Si. Investigation of the c of the Mn-Si alloy system showed that . Mn3Si(14.55% Si) is polymorphic. Phase transformation occurs at appx. 6200 and is accompanied by a Joule effect of the order of 8.0 cal/g. The coefficient of linear expansione(was measured in the 20-3500 interval by means of the Chevenard photographically -recording differential dilatometer. For technically pure Si, the experimental data may be described by the e- quation 1060(= 3.1395+1.914xlo-3t-0.0945xlo-6t?. Analogous equations are adduced for a number of alloys of the Fe-Si and Cr-Si systems. The iso- therms of the coefficient of linear elongation exhibit maxima in the regions of the9and F-phases of the Fe-Si system and in the 50% Si inteTval of the Cr-Si system.

Diskus. , pp 408-409" ABSTRACT: The thermo-emf, E, of Fegi-,- Cr-Si-, and Mn-Si alloys is investigated in accordance with the constitutions thereof. Mea 'surements were made on a Korzh instrument (Zavodsk. .-lab. 1948, Vol 14, p 107). E is negative and smaW (not over 1.58mv at 1000C) for Fe alloys containing 4-6% Si. As the Si contents increase the E diminishes, reaching 0 at 17% Si. At 17-59% Si, E is positive, negligible in value, and little dependent upon the constitution of the alloy. A change in the Si content from 57 to 59% causes E to change from 0. 67 mv at 1000 to 0. As the Si contents are further increased, E becomes negative, and its value increases, In the case of Card, I/Z cast (99. 2%) Si, E is 51-60 mv at 1000. In Si-Cr alloys the 137-58-2-3810 Thermoelectric Properties of Alloys (cont. E of pure Cr is+O. 6 mv at 1000. As the Si content is increased, the E diminishes, changes sign, and is minus (0. 9-1. 0) mv at 1000 for 10% Si. Subsequently E diminishes rapidly and acquires negative values. The E curve for Mn-Si alloys reveals points of inflection corresponding to stoi- chiometric constitutions and regions in which the chemical compounds are stable. The correlation between the F curves and the fusibility curves of the systems was found. It is assumed that alloys with -negative E have a larger number (per unit volume) of small crystals with small n-type con- ductivity. The E of various modifications of lebowite in the sigma phase of Fe-Si were investigated. The low-temperature modification thereof has a positive E of 0. 3-0. 6 my at 1000, which is little dependent upon the Si content. The equilibrium 27, is readily hardened at 650-9080 and is characterized by high E value;~, strongly dependent in magnitude and sign upon the Si contents, at room temperature. The E of t;c (9200) depends upon the concentration of the alloy in magnitude and sign. A. M. 1, Silicon alleys-Thernoelectrie properties 2. Manganene-dilicon alloys -Thermoelectric pi-operties 3.

Ural' skogo politekbn. in-ta, 1957, Nr 72, pp 105-120 ABSTRACT: Alloys of the type Fe-Si, Cr-Si, and Mn-Si were investigated throughout the full range of concentrations. Investigated in greater detail were Fe-Si alloys of a composition close to that of I'lebowite" (40-600/o Si). The initial materials used were Armco-Fe, electrolytic Cr, and 99. 2-pure crystalline Si. Cylindrical specimens 2 mm in diameter and 40-50 mm long were obtained by drawing the melt from the crucible of an induction furnace into a thin quartz tube. The integral thermo- e. m. f. E was measured with the aid of the apparatus described earlier (Korzh, P. D. , Zavodskaya laboratoriya, 1948, Vol 14, p 207) with an accuracy of up to 0. 05 mv. It is established that, in an Fe-Si system, E is negative up to 4-60/o Si and that it Card I/Z attains a maximum of 1. 5 mv/1000C. Upon a further increase SOV/137-58-7-15613 Thermoelectric Properties of Alloys (cont. ) in the concentration of Si, the absolute value for E decreases and at 1770 Si it equals zero. Specimens containing 17 to 590/o Si have a positive E insig- nificant in value and depending very little on the composition. In alloys con- taining >590/o Si, E is negative and its numerical value increases rapidly on the enrichment of the alloy with Si, which is characteristic for semiconduc- tors. The qualitative relationship of E to the composition is the same in Cr-Si and Mn-9i alloys as in the Fe-Si alloy. In all of the alloys the relation- ship between E and the composition corresponds to the phase diagram. The rectifying action of alloys rich in Si was investigated. Depending upon the location of the point contact either p-type or n-type conductivity was discov- ered which points to the microheterogeneity of the specimens, possibly re- lated to an uneven distribution of impurities and a corresponding presence of impurity conductors with carriers of either type. The alloy with 51. 0070 Si has a semiconductive nature. It is assumed that CrSi2 (51. 807o Si), in contrast to other silicides, possesses detector properties. Bibliography: 20 references. 1.

The samples were prepared-from manganese (containing less than 0.05% impurities) and KM-1 silicon. Alloying was carried out in an evacuated and sealed quartz flask in a high frequency induction furnace. Alloys'containing 44 to 55% Si were prepared. Metallographic, X-ray and thermal analysis was carried out. When viewed b'y polarized light und-er the microscope, the alloy containing 44% Si consisted of an optically active matrix of a higher silicide (MnnS'2n-x) with optically inactive inclusions of monosilicidti. With increasing Si content, the quantity of monosilicide decreased. The microhardness of the higher silicide was 1050 kg/,MM2 and that of the monosilicide 850 kg/mm2. An alloy containing 46.5% Si was single-phased'. Traces of a new Card 1/3 - 26563 S/126/61/012/002/013/019 The phase constituents ... E021/E480 phase appeared at 47% Si- The new phase was optically inactive And similar to silicon in colour. An alloy with 49% Si had a coarse grained structure with a eutectic precipitate inside the grains. The alloy with 51.5% Si was practically all eutectic. Primary crystals of Si appear in samples with greater than 51.5% Si. The eutectic temperature was 11450C- A oeritectic transformation occurs at 11500C and 48.8% si.

TITLE: The martensitic transformation in Mn3S1 PERIODICAL: Fizika metallov i metallovedeniye, v. 12, no- 3, 1961, 424 - 430 TEXT: It would be of great interest to establish whether martensitic diffusionless processes of the type observed in wustite (Ref. 4 - R. Collongues - Acta Cryst., 1954, 7, 213) occur in other oxides, carbides, borides, nitrides and silicides. This would further substantiate the views of G.B. Kurdyumov (Ref. 5 - Problems of Metallurgy and Metal Physics, Sbornik 3, Metallurgizdat, Moscow, 1952) on the universality of martensitic transformations. Davydov and Geltd (Ref. 7 - Tr. UPI, 1957, Sb. 67, p. 96) have previously shown that the lowest silicide of manganese undergoes a phase-transformatlon over a somewhat extended temperature range, giving considerable property changes. Quenching of specimens containing Mn3Si changes their properties and heating for 3-5 min at or over 400 C causes the density to rise to values higher than reported (Ref. 8 - R. Frilley, Card 175 30455 s/126/6i/ol2/003/014/021 The martensitic transformation ... EIl1/E335 Rev. Metall., 1911, 81 468). The authors report additional metallographic and X-ray structural investigations of an alloy with about 14-5 wt-o% Si, carried out to establish the nature and peculiarities of this transformation. The alloy was induction- melted from electrolytic manganese (over 99.90% Mn) and purified technical silicon (over 99.2% Si) and homogenized at 1 020 0c for 90 hours. Before testing, some specimens were annealed at 500 C and others were water- or alr-quenched from 800 OC. Polished sections were etched in a 40/'D solution of hydrofluoric. ac-ld in alcohol.. The annealed alloy consisted of fairly coax-se polyhedral Mn3Si grains lined, probably, with Mn 5Si 3' The water-quenched specimen had a structure typical of martensite- transformation products; this was less pronounced in the air- quenched and 'absent in the slowly-cooled alloy. The martensitic phase thus formed recrystallizes easily. Vacuum-heating to 800 oC of a polished section of a previously annealed alloy gave a relief characteristic of martensitic phases. X-ray investigations, carried out in CrKa,p radiation gave a lattice Card 2/5 30455 S/126/61/012/003/oi4/021 The martensitic transformation ....

The Deby,e patterns of annealed and quenched alloy powders ifere identical. To elucidate the reproducibility of crystallographic orientations obtained under various conditions, special experi- ments were carried out. The snecimen was mounted in a miniature furnace, in a type KPOO-I (I~POS-I) camera, 62 imn from the film. The beam was passed through two 0.8-mm diameter diaphragms. Spot.:F obtained at an angle of 78.60 were registered on a flat film. S4 -gnificant differences as well as similarities -%%rere found in the patterns obtained from an annealed specimen and from the same spot of the specimen vrater-quenched from 750 OC. Additicnal spots on the pattern of the quenched specirrien can be related to the needle-like structural component. This and other evidence indicates that the needle-phase occupies most of the volume in th~z quenched alloy and that the needles (or plates) are mutually Card 3/5 30455 S/126/61/012/003/01-4/021 The martensitic transformation .... E111/E335 ordered. In another series, the patterns were obtained at a specimen-film distance of only 30 mm, at various temperatures from specimens subjected to various treatments; both factors influenced the pattern. Interpretation is made difficult by insufficient information on the phase diagram of the Mn-Si system and absence of high-temperature Debye patterns. The existence of a transformation, probably polymorphic, in Mn3Si on heating at about 600 - 650 0C has, however, been confirmed. The tran6for- mation is martensitic on rapid and diffusional on slow coolin&. The nature of the0previously observed dilatometric and thermal effects near 400 C remains obscure and further high-tcmpz~rattire X-ray work is needed.

He succeeded,,by selective breeding, in raising the percentage of oil from the original 33% (re- garded as the highest possible percentage), to 36% and subsequently to 54%. Since 4.5 million hectares are annually seeded to sunflowers in the USSR (more than 3/4 of the entire acreage of crops producing vegetable oil), the work of V.S. Pusto- voyt is of great importance to the national eco- nomy of the USSR.

In 1923, V.V. Kuybyshev opened the first permanent industrial ex- hibition in this building. This exhibition illustrated the achievements of Soviet industry. Since then, this exhibition has been improved and has become a center for propagating the progress and success in the scientific and technical field, and for exchanging first-class experience gained in industry. Seminars are held here on various technical and scientific subjects, and are attended by students from all classes of society. Vladimir Mikhaylovich Gerst is director of the House. In 1948, Professor V.K. Prokoflyev held here the first semi- nar on spectral analysis. Various industrial enterprises have access to the findings of the work done in these semi- nars, and thereby improve their working methods. For example, the results achieved in the seminar of the Dotsent P.V. Kamnev Card 1/2 are responsible for a 60-70% increase in the productivity of Kevskiy Prospekt, 56 25-8-14/42 the Leningrad foundries.

TITLE: Magnetic spectra of cobalt-zinc ferrites SOURCE: Fizika tverdogo tela, v. 6, no. 7, 1964, 2190-2192 TOPIC TAGS: cobalt, zinc, ferrite material, anisotropy, magnetic permeability, dispersion characteristic, frequency dependence ABSTRACT: Inasmuch as earlier investigations were confined to ferrites with negative anisotropy constants, the authors attempted to obtain compositions with high initial permeability based on a ferrite with a-large anisotropy constant. Cobalt ferrite with spinel-type structure was chosen as the initial material. To check whether the series of.solid solutions Co 2+ Me 2+ Ele 0 includes some 1-x x 2 4 with large initial permeability if Zn 2+ is used as the diamagnetic Card ACCESSION NR: AP404173~ 2+ ion Me , the authors prepared solid solutions of the system (1-X)COFe 0 - ZnFe 0 containing from 0 to 90% ZnFe 0 (in steps of 2 4 2 4 2 4 10% except near the maximum permeability, where steps of 5% were used). The rbsults showed a maximum of initial permeability (38) at x = 0.55., Magnetic spectra were also measured for all specimens at frequencies from M to 4000 Mc/sec. The results showed that an increase in the Zn content leads to a shift of the dispersion band toward lower frequencies, indicating.a decrease in anisotropy. The measurement procedure is described briefly. it is concluded tl~at a positive anisotropy constant contributes to an increase in initial permeability, that the initial permeability increases with increasing zinc content.

These two people represent two generations, as Itt were. Khimich was a member of the plant already at the time of the 1st Five-Year Plan. He and his collaborators built the famous rail-structural mill ofNizbrLV -'_-qzlj~Later he was in charge of the oonstruction of the decond rail-structural mill, which was intended for India. And in this work, Bykov also had a share. Here, he was given an opportunity to show how capable adesigner he was. This second rail-structural mill actually surpassed the first by far. The designers succeeded in automating the mill to a higher degree. At the same time, this permitted to mpkA it much lighter, and 1000 tons of metal were saved. A number of designers employed at the Uralmash plant, and among them Bykov, visited some metallurgical enterprises and studied rail-structural mills in operation. They found that there were Card 1/3 some discrepancies between the individual elements of the mill. A Thousand Tons SOV ,/29-58-11-14/28 It is known that a rail-structural mill consists of a long row of individual machines which are connected by means of roll tables. The latter as well as the scaffoldings did not come up to the production requirements. Since they were of different sizes they were not properly adjusted to each other and required too much manual work. Bykov attempted to bring these discrepancies to a common denominator. He designed a new type of rollers smaller than had been used so far. These rollers have been substituted for all other types of rollers. They are not rollers for one particular rolling operation, but are individual parts which can be made up into any kind of roll tables. The same standardization was carried out in the case of the scaffoldings. Instead of fifteen different kinds of plates one single type can now be used. The result of these streamlining operations was that the mill as a whole became much simpler in structure and much lighter. This principle was the-n applied to other machines. The young designer Oleg Sokolovskiy designed exchangable scaffoldings. This resulted in a reduction of weight of another 100 tons. Designers Khimich, Krivonozhkin, Yefimov and Bykov developed 7 Card 2/., an original roller adjuster which again reduced the weight i Thousand Tons SOV/29-58-11-14/28 of the entire plant. Earlier the designer P. A. Antonov introduced over-all automation of the plant. So each of the designers employed at the Uralmash plant has had his share in reducing the quantity of metal used by 1000 tons. Among these persons to be mentioned there are also the young designers V, Niskovskiy and A. Varaksin, who designed a new tilting device, and N. Mankevich, who automated the checking platforms.
