针对应力应变对马氏体相变动力学及相变塑性的影响进行了研究,得到了应力作用下相变动力学和相变塑性的计算模型,而且发现相变前预应变限制了相变塑性的数量和相变反应的速度,使之不能用弹性状态下得到的模型进行简单的外推,并利用应力应变诱导相变、母相强化等理论进行了解释
The influence of stress and strain on martensitic transformation kinetics and phase transformation plasticity was studied. The calculation model of phase transformation kinetics and phase transformation plasticity under stress was obtained, and it was found that pre-strain before transformation limits the amount of phase-change plasticity And the speed of the phase change reaction so that it can not be simply extrapolated using the model obtained under elastic conditions and explained using the theories of stress-strain induced phase transformation and matrix strengthening
