Abstract：The M_s temperatures of Fe-Mn-C alloys have been calculated by the appli- cation of LFG model of △G~(γ→α) with Mogutnov's △G_(Fe)~(γ→α),Hsu-A model with Orr-Chipman's △_(Fe)G~(γ→α) and Hsu-B model with Orr-Chipman's △G_(Fe)~(γ→α) and are in good agreement with the experimental values.Through the mathematical treatment, the relationship between Ms and the composition of Fe-Mn-C alloys can be ob- tained as: M_s(K)=817.4-7513.4x_C-4141.9x_(Mn)-32083.5x_cx_(Mn) (LFG model with Mogutnov's △_(Fe)G~(γ→α)); M_s(K)=829.9-7580.5x_C-4166.0x_(Mn)-15727.Sx_cx_(Mn) (Hsu-A model with Orr-Chipman's △G_(Fe)~(γ→α)); M_s(K)=829.2-7276.1x_C-2915.4x_(Mn)-43825.7x_cx_(Mn) (Hsu-B model with Orr-Chipman's △G_(Fe)~(γ→α)) in which the linear correlation coefficient of these relations are larger than 0.992. Both C and Mn depress M_s linearly and the effect of C is almost two-fold stro- nger than that of Mn.Introduction of an interaction term(x_Cx_(Mn)) between alloying elements in the present treatment shows that C and Mn enhance the effect upon M_s of each other.The driving force for transformation increases monotonically with C and Mn content and there is no singularity.The ealculted M_s and the driving force largely depend on the △G~(γ→α) model and △_(Fe)G~(γ→α) values adopted. 收稿日期: 1987-01-18      服务 把本文推荐给朋友 加入引用管理器 E-mail Alert RSS 作者相关文章 张鸿冰 倪乐民 徐祖耀 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1987/V23/I1/42 1 Zener C.Trans AIME 1946;167:550 2 徐祖耀,金属学报,1980;16:426 3 Fisher J C.Trans AIME,1949;185:628 4 徐祖耀,金属学报,1979;15:329 5 Hsu T Y(Xu Zuyao),Chang Hongbing.Acta Metall,1984;32:343 6 Hsu T Y(XU Zuyao),J Mater Sci,1985;20:23 7 Nichol T,J,Judd G.Ansell G S.Metall Trans,1977;8A:1877 8 Kato T,Fukui S,Fujikura M,et al.Trans Iron Steel Inst Jpn,1976;16:673 9 徐祖耀,张鸿冰,罗守福,金属学报,1984;20:A151 10 Hsu T Y(Xu Zuyao),Chang Hongbing,Luo Shufu,J Mater Sci,1983;18:3206 11 Shifler G J,Bradley J R,Aaronson H I.Metall Trans,1978;9A:999 12 Zener C.Trans AIME,1955;203:619 13 Mon Yiwen,Hsu T Y(XuZuyao).Acta Metall,1986;34:325 14 Aaronson H I,Domain H A,Pound G M.Trans Metall Soc AIME 1966;236:768 15 Greninger A B.Trans ASM 1942;30:1 16 Kaufman L.Radcliffe S V,Cohen M.In:Zackey V F,Aaronson H I.eds.,Decomposition of Austenite by Diffusional Processes.Interscience Publ,1962;313 17 Andrew K W.J Iron Steel Inst,1965;203:721 18 Kung C Y,Ratmet J J.Metall Trans,1982;13A:328 19 徐祖耀,马氏体相变与马氏体,科学出版社,1981,237 20 Lobo J A,Geiger G H.Metall Trans,1976;7A:1359 21 Wada T,Wada H,Elliott J F et al.Metall Trans 1972;3:1657 22 Hultgren R,Desai P.D,Hawkins D T et al.Selected Values of Thermodynamic Properties of the Elements,Ohio:ASM,1973,171 23 Breedis J F,Kaufman L.Metall Trans,1971;2:2359 24 徐祖耀,金属学报,1980;16:420 No related articles found!
