摘要
基于马氏体相变热力学和亚点阵模型,建立了Fe-C-Mn-Si系合金马氏体相变自由能表达式,并利用Compaq VisualFortran 6软件对其进行编程;应用Thermo-Calc软件及TQ6接口模块并结合大量实验数据,对计算参数进行优化,获得马氏体相变临界驱动力与Fe-C-Mn-Si系合金成分的关系式。采用该方法可较为准确地预测Fe-C-Mn-Si系合金的马氏体转变开始(Ms)温度,并有望推广到更多元合金体系。
Based on martensitic transformation thermodynamics and sublattice model,ΔG γ→M of Fe-C-Mn-Si alloy was deduced and programed by Compaq Visual Fortran 6 software.The parameters of expression were optimized by the aid of TQ6 interface module in Thermo-Calc software combined with experimental results.The relationship between martensitic transformation critical driving force and composition of Fe-C-Mn-Si alloys was obtained.Then Ms temperature of Fe-C-Mn-Si alloys can be accurately predicted by computational method,which can be extended to more complex multicomponent alloy system.
