摘要
在马氏体相变热力学与亚点阵模型基础上建立了Fe-C-Mn-Si-Cr系合金的马氏体相变自由能表达式,并采用Compaq Visual Fortran 6.5软件编写五元系计算程序;应用Thermo-Calc软件及TQ接口模块并结合大量实验数据,优化并计算Fe-C-Mn-Si-Cr系马氏体相变临界驱动力与合金成分的关系式,从而准确预测Fe-C-Mn-Si-Cr系合金的马氏体开始转变温度。
Based on martensitic transformation thermodynamics and sublattice model, △Gγ-M of Fe-C-Mn-Si-Cr alloy was deduced and the calculation process was programmed by Compaq Visual Fortran 6.5 software. The relationship between △Gγ-M and composition of Fe-C-Mn-Si-Cr alloys was obtained through the optimization of inter-parameters combined with experimental results by using Thermo-Calc software and TQ Interface. The use of such method could provide an accurately prediction to Ms temperature of Fe-C-Mn-Si-Cr alloys by thermodynamics.
