试图合理化关于奥氏体晶粒尺寸对钢中贝氏体转变整体动力学影响的一些相互矛盾的观察结果。对两种钢进行了实验，结果表明奥氏体晶粒尺寸对反应速率有相反的影响。通过考虑每种钢中贝氏体的形态，推导出描述反应速率的一般方程。推导的方程可以解释奥氏体晶粒尺寸对总反应速率的矛盾影响。结果也被发现是在良好的协议与公布的数据。MST/4135
An attempt is made to rationalise some contradictory observations on the effect of austenite grain size on the overall Kinetics of the bainite transformation in steels. Experiments have been carried out on two steels which show opposite effects of austenite grain size on the reaction rate. General equations describing the reaction rate are derived by taking into account the morphology of the bainite in each steel. The equations derived can explain the contradictory effects of the austenite grain size on the overall reaction rate. The results are also found to be in good agreement with the published data.
