对变形过程中产生马氏体相变的亚稳态材料，通过修正Olson模型提出了一个新的模型定义为混合物交互作用强度法则。新模型一方面利用奥氏体、马氏体的幂乘硬化曲线取代直线假定；另一方面考虑了基体与转变相的交互作用，增加了交互作用项I()，得出的混合物强度法则新模型为=c－I(), 其中I()=74.4(df/d)--55.6。利用新模型计算得到的理论值与实验值符合得相当好。
A new model on the mixture law for predicting strength of metastable materials with martensite transformation has been proposed from modifying Olson model. In the new model, firstly, the power curves of austenite and martensite has replaced the straight line in Olson model; secondly, an interaction based on the interaction of austenite and martensite has been added.Results show that the values obtained by our model are better agreement with the experimental ones than other models.
