Fe-C间隙固溶体热力学模型

A Re-Examination to the Thermodynamic Models of Fe-C Interstitial Solutions

摘要: 详细考察了目前文献中常用的几种Fe-C间隙固熔体热力学模型,并讨论了它们在钢中马氏体及贝氏体相变中的应用情况。首次表明KRC、LFG/MD以及X-K模型均不能用来建立奥氏体与马氏体中是否发生Spinodal分解的热力学判据。

Abstract: The currently used thermodynamic models for the Fe-C interstitial solutions have been examined in detail for the first time. Results show that none of KRC, LFG/MD and X-K models can be employed to establish the thermodynamic criterion for the spinodal decomposition in austenite and ferrite (martensite) in steels.
