在以往工作基础上,提出多元低合金钢马氏体相变热力学方程式: 用数学和实验方法证实了这个计算式,并指出联系动力学方程后,可用以计算淬硬钢的残余奥氏体量。 Based on the previous work, the thermodynamic equation of martensitic transformation in multivariate low-alloy steels was put forward. The formula was verified by mathematical and experimental methods. It was pointed out that the kinetic equations of residual martensite could be used to calculate the residual austenite .
