Fe-C間隙固溶體熱力學模型

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

摘要: 詳細考察了目前文獻中常用的幾種Fe-C間隙固熔體熱力學模型,并討論了它們在鋼中馬氏體及貝氏體相變中的應用情況。首次表明KRC、LFG/MD以及X-K模型均不能用來建立奧氏體與馬氏體中是否發生Spinodal分解的熱力學判據。

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.
