摘要：

In accordance with the microthermodynamics, the relationship among critical resolved shear stress (CRSS), stacking fault energy (SFE) and strength was discussed. The comprehensive function of the alloying elements decides the martensite transformations of gamma-->alpha, gamma-->alpha+epsilon or gamma-->epsilon, which results in relevant changes of martensite transformation critical points M-s and M-epsilons. Based on the experimental results and theoretical analysis, the quantitative expressions of M-s and M-epsilons were established with the aids of the computer. These expressions can be applied to engineering and the design of martensite transformation temperatures for cryogenic austenitic steels. (C) 2004 Elsevier Inc. All rights reserved.
