摘要
本文研究了40Cr 钢原始组织和加热转变温度对奥氏体起始晶粒的不均匀因子 Z_0的影响,并以已知的转变动力学理论为基础推导了奥氏体起始晶粒不均匀因子 Z_0。试验所得结果除原始组织晶粒大小的影响外均与理论推导符合得很好。
In this paper the influence of prior structure and transformation temperature
on the nonuniformity factor Zo of initial austenite grain was investigated
with steel 40Cr,at the same time Zo was derived on the basis of known theory
of transformation kinetics.The experimental results coincide with theoreti-
cally derived value very well except the influence of grain size.
