在评述以在工作的基础上,就目前对马氏体相变的认识提出进一步处理的概念。着重对下式的物理含义加以阐述, ΔG~(γ→M)=ΔG~(γ→a)+Δ~(α→M)提出对ΔG~(α→M)估计的概念及运算途径。改进了处理方法并以较新数据计算了ΔO~(γ→a)。由热力学处理直接求得的理论M_s值与典型实验值很好符合,指出纯铁的M_s应为800K,Fe-C合金的M_3与碳浓度及奥氏体在M_s时的屈服强度均呈线性关系;相变驱动力随碳浓度的增大及M_s的下降而增加。
On the basis of his work, he commented on the concept of further processing on the current understanding of martensitic transformation. The emphasis is put on the physical meaning of ΔG ~ (γ → M) = ΔG ~ (γ → a) + Δ ~ (α → M). The concept of ΔG ~ (α → M) The processing method was improved and ΔO ~ (γ → a) was calculated with newer data. The theoretical M_s value obtained directly from the thermodynamic treatment is in good agreement with the typical experimental values, indicating that the M_s of the pure iron should be 800 K and the M 3 of the Fe-C alloy has a linear relationship with the carbon concentration and the austenite yield strength at M_s The driving force of phase transformation increases with the increase of carbon concentration and the decrease of M_s.
