3 ) a novel martensitic transformation kinetics model for sma is proposed based on the phenomenological description of the martensitic transformation heat flow - temperature curve and on the linear relationship between the partial derivatives with respect to the temperature of martensite fraction and of gbbis free energy . numerical simulations by utilizing the proposed model are closer to experimental results than those from other models 3 )基于对马氏体相变热流-温度实验曲线的唯象模拟，以及马氏体体积分数与热力势对温度偏导数之间的线性关系，建立了一种新的马氏体相变动力学模型，并与其他模型及实验结果进行了比较。
The effect of plastic deformation and elastic strain energy induced by pre - strain on the nucleation of martensitic transformation of low alloy ultra - strength steel sosimncrmov had been studied by pre - strain quenching in austenite state . the control over deformation magnitude and deformation temperate as well as loading pattern was performed to adjust the storage of elastic strain energy in steel before martensitic transformation , using the type of geeble - 1500 thermal analogue test machine 使用gleeble - 1500型热模拟机，对低合金超高强度钢30simncrmov实施奥氏体预应变淬火处理，通过控制形变量、形变温度和加载方式，调整钢中马氏体相变前的弹性应变能储备，研究了预应变所造成的塑性变形与弹性应变能对马氏体相变的影响。
