V. Shultin, F. F. Khimushin, F. M. Becket (Ref. 1, 2, 7), G. V. Estulin (Ref. 3) ; A. T. Grigorlyev, D. L. Kudryavtsev (Ref. 4, 6) and foreign scientists (Ref. 8-10). In the present article Information-is given on the effect of manganese and chromium on phase transformations in steel. In a 12-kg induction furnace, 16 alloys with different chromium and manganese content and one chrome-nickel alloy containing Ti were melted. Changes in hardness attEm water quenching at 800, 9D0, 1,000, 1,100 and 1,2000C were studied. The dependence of the hardness on temperature is shown in Table 3. After q7aeric-hirg card 1/4 s/167/6o/0oo/0o4/bol/003 AOc6,/Aool The Effect of Chromium and Manganese on Phase Transformations of Chrome-Manganese Steels the specimens were subjected to an analysis of the microstructure. The steels were tempered at 650, 700, 750 and 8000C. Changes In H , depending on the tempering time of steels with 17% Cr, quenched at 1, 10A a9 gien in Table 4. The connection of a possible ~-phase formation and higher hardness wass deter- V mined by investigating the magnetic properties of the sterl. Specimens of all steel melts were analyzed on an M. S. Akulov type anisometer at, 20 after tempering at 7500C. for 10 hours. 'I"he amount of a ferromagnet�c phase was deter- mined for various steel grades. Dilatometrioal a:nalysis was made on Chrome- manganese specimens quenched at 1,1000C with subsequent wmealing at 750 OC for 10 hours. Curves of temperature versus linear expansion for 4,-ArGa grades of steel with 10% Cr were plotted (Fig. 2). A phase analysis was'made of precdpi- tates out of an electrolyte on saturated potassiam chloride base with FidcUtion of 5 to 50 mg/l hydrochlori8 acid and 5 to 25 9/1 critic acid at a c4urrent density of 0.6 - 1.0 amp/cm and a temperature not over 2000. A copper cylinder was used as a cathode. 9 to 12 mm specimens were placed Into a cocilodlon bag filled with 100 - 130 ml of the filtrated electrolyte.

Roentgenograms were taken of the dreid precipitates with a PKA (M) camera on Cr radiation without using a filter. Exposure time was 13 to 18 hours. A chemical analysis was made of precipitates separated'out of 4 steel grades in an electrolyte composed of 250 g/l potassium chloride, 5 rre/I hydrochloric acid, 5 9/1 citric acid, 0.6 - 0.8 amp/cm2 current density. and 18 - 220C inside the collodion bag. The investigations performed yielded the following results. At a content of 11% Mn, independent of the chromium content, the steel contains in its structure austenite as well as ferrite. It is not possible to convert the steel into the austenitic state by hee. treatment. Steel with 16 - 022% Mn and 8 - 10% Cr has a ~ + E-structure at temperatures below 140 - 210 C and an austenitic structure at a temperature over 2100r'. -1'he presence of the F--phase was not observed in steel with 27% Mn. In steels wit-11 13 and 17% Cr, independent of the manganese content, the structure is com osed 8, of ferrite and austenite after quench-hardening at a temperature over 900 ~. The amount of ferrite in the steel group with 17% Cr is considerab2,y higher than Card 3/4 S/167/60/000/004/001/003 A006/A001 The Effect of Chromium and Manganese on Phase Trans formations of Chrome-Manganess Steels that of steels with 13% Cr. After heating to 600 - 9000C, the ferrite Is decomposed and the ~*-phase is formed (except X13r11 (KhOG11)11and X17rll (Kh17GWill steels). Steels with 17 and 13% Cr contain carbide of the %3~D6 type whl-~h may be expressed by the formula (Fe, Mn, Cr)2P6. There are 5 tables, 2 ftTarss and 11 references, 6 Soviet, 2 English and 3 erman.

For their own investigation of the strength and plasticity of euch alloys the authors used the following range of compositions, %: 4.87-16.82 Al; 0.005-0-094 Mn; 0.013-0-100 Si; 0.02-0.05 S; 0.002-0.012 P; 0.018-0.020-C; 0.002-0.015 0; 0.004-0.011 N; (not all the S and P analyses were carried out). The alloys were melted in a vacuum induction furnace described by Kashin et al. (Ref.9j" or in air from aluminium-deoxidized Armco iron and grade ABOOOO (AVOOOO)aluminium.

Impact strength as function of the test temperature is shown in Card 1/3 W76 S/180/60/000/005/017/033 Ellr/E135 Some Properties of Iron-Aluminium Alloys Based on the a-Solid Solution Fig.2 and the cold brittleness threshold (temperature at which the alloy acquired an impact strength of 2 kg/cm2) as a function of aluminium content in Fig.3 (air-melted alloys represented by interrupted lines in both figures). For tensile testing at 20-700 OC a typelwl-4P machine was used. Tensile strength, yield point and relative elongations, as functions of aluminium content for various temperatures, are shown in Fig.4. Fig.5 shows relative elongation as a function of temperature for air- and vacuum-melted alloys (right- and left-hand graphs). Grain size as a function of holding time at 1100 00 for vacuum-melted alloys is shown in Fig.6. The influence of heating temperature on hardness for two alloys with 15% Al is shown in Fig.7 (air- melted, curve 1; vacuum-melted curve 2): the hardness of both has a maximum at about 350-450 6C,-but rises much more steeply and attains a higher value with vacuum melting. Vacuum melting also improves other high-temperature properties of Fe-Al alloys.

Maximum strength and adequate plasticity are obtained at 400 OC; above 600 OC strength falls sharply while plasticity increases.

TITLE: Influence of aluminum and carbon on properties of steel with 10 ~ Or and 13 % Mnp at elevated tempera- tures SOURCE: Akademiya nauk SSSR. Institut metallurgii. Issledo- vaniya po zharoprochnym splavamv v. 7, 1961, 317-328 TEXT: The influence of Al addition in the range of 2.35 - 4.67 % and of C in the range of 0.1 - 0.8 % was investigated in 10 % Or and 13 % Mn steel in which the appearance of the cr-phase is ex'clu- ded. The saMDles were prepared by smelting in a magnesite crucible, in an induction furnace, and consisted of Armco iron, Or;, Mn (96.5% pure) and Al metal. C was introduced by addition of synthetic cast iron. The ingots were forged into cylinders of 12 and 20 mm diame- ter,,,.starting the forging at 11500 - 12000C eliding at 75000. The samples were then hardened by quenching in water from 9500C for 2 Card 1/3 S/659/61/00-7/000/039/044 Influence of aluminum and carbon D205/D303 hours prior to testing. The resulting structures were: Without Al and with 0 1 % M, with 2o5 % Alt Oo4 %,0'(V) and with 2.5 % Al. 0.8 % C (Vi) . These steels were austenitic.' With 2.35 % Al and 0 1% C (II) the structure was 65 % austenite 35 % ferrite; with 3.12 Alp 0.1 % C (III) - 90 % ferrite; with 4.67 % Alp 0.1 % C (IV) 100 % ferrite. The temperature dependence of strength and plastici- ty was examinedp using an ~~I-P (IM-4R) machine. The,hot hardness was examined at 7000, 8000 and for samples V and VI also at 9000C, on the 3MM -HM (VIM-IM) apparatusq using a sap hire identor. Resis- tance to creep was examined on the on-2 (IP-2~ and IP-5 machinesp using stresses of 9 kg/mm2 in the temperature range of 550 - 7500C. Resistance to scaling was examined by the weight gain of samples heated for various times in muffle furnaces in the 900 - 12000C temperature range. The austenite of the 10 % Crp 13 % Mn and 0.1 %C steel is unstable and is transformed into martensite under the ac- tion of plastic deformation. Aluminum exerts a high ferrite-forming action and lowers the high-resistance characteristics. Exploiting the y-forming ability of carbon, the austenitic structure can be achieved in steel containing aluminum. 0,,4 % of C in the presence Card 2/3 B/659/61/007/000/039/044 Influence of aluminum and carbon ... D205/D303 of 2o5 % Al gives a stable austenitic structure. The re~-,Istance of this steel (V) is higher than that of the other investigated steels. The resistance to scaling increases sharply with an increa- se of Al -content. The increase of C up to 0.4 % lowers the resis- tance to scaling. Further increase of C to 0.8 % has little bearing in this respect. Steel (V) has good heat and scale resistances up to 7000C and can be used for durable service under stress up to 6500CP instead of Cr-Ni steel 1X18H9T (1Kh18N9T).
