本文针对16MND5钢中的马氏体相变，指出了相变后果的实验结果与模拟结果之间的一些差异。分析了三种现象：从冶金角度分析表明，即使停止冷却，也可能发生马氏体相变。这一观察结果与Koistinen和Marburger‘State’规则的预测不一致。。与预期相反，在相变过程中，奥氏体相的应变硬化似乎没有传递到马氏体相。。在无外加载荷的马氏体相变过程中，由于奥氏体相的塑性预变形，观察到了相变塑性。结果表明，观测到的效应不能用Leblond模型定性地描述。
In this paper some discrepencies between experiments and modeling of the phase transformations consequences are pointed out considering the martensitic transformation in a 16MND5 steel. Three phenomena have been analysed: . From a metallurgical point of view, it is shown that martensitic transformation may develop even if the cooling process is stopped. This observation disagrees with the forecasts of Koistinen and Marburger 'state' rule. . Contrary to what it can be expected, the strain hardening of the austenitic phase seems to not be transmitted to the martensitic phase during the transformation. . During martensitic transformation without any external load, transformation plasticity is observed due to a plastic predeformation of the austenitic phase. It is shown that the observed effect cannot be qualitatively described by Leblond's model.
