摘要

建立了一个模型来模拟马氏体钢回火过程中渗碳体的析出动力学，特别关注渗碳体/马氏体生长界面上溶质分配行为从初始准平衡（PE）到正平衡（OE）条件的自发转变。讨论了这种转变对生长动力学的影响，并与实验数据进行了比较。

Modeling of Spontaneous Para-equilibrium to Ortho-equilibrium Transition in Cementite Precipitation During Martensite Tempering

A model has been developed to simulate the precipitation kinetics of cementite during the tempering of martensitic steels, with a particular focus on the spontaneous transition of the solute partitioning behavior at the cementite/martensite growth interface from initial para-equilibrium (PE) to ortho-equilibrium (OE) conditions. The effect of this transition on the growth kinetics has been discussed and compared with experimental data.

期刊介绍： The most trusted journal for phase equilibria and thermodynamic research, ASM International''s Journal of Phase Equilibria and Diffusion features critical phase diagram evaluations on scientifically and industrially important alloy systems, authored by international experts. The Journal of Phase Equilibria and Diffusion is critically reviewed and contains basic and applied research results, a survey of current literature and other pertinent articles. The journal covers the significance of diagrams as well as new research techniques, equipment, data evaluation, nomenclature, presentation and other aspects of phase diagram preparation and use. Content includes information on phenomena such as kinetic control of equilibrium, coherency effects, impurity effects, and thermodynamic and crystallographic characteristics. The journal updates systems previously published in the Bulletin of Alloy Phase Diagrams as new data are discovered.
