共析碳钢过冷奥氏体-珠光体转变的理论计算

THE THEORETICAL CALCULATION ON THE TIMETEMPERATURETRANSFORMATION CURVE OF THE CARBON EUTECTOID STEEL

据晶体相变的成核理论及晶体原子扩散的计算，定量地推导出了共析碳钢的过冷奥氏体－珠光体转变的时间－温度－相转变开始的函数关系式。与此相变的实验曲线的定量比较表明：推导与实验曲线在形状上符合。

The Time-Temperature-Transformation relation for the carbon eutectoid steel is deduced theoretically,based on the theory of diffusion and the theory of the heterogeneous nucleationThe deduction is agreeable to the experimental results
