摘要
将Feder相变孕育期表达式引入形变奥氏体的分解中,建立了奥氏体形变条件下先共析铁素体等温形成孕育期的计算方法,计算了奥氏体形变储能和奥氏体晶界能量变化对相变孕育期的影响,计算结果与实验所得规律一致。
A calculation method for the isothermal nucleation incubation time
of pre-eutectoid ferrite from deformed austenite has been developed by introducing
Feder's incubation time expression into the decomposition of dsformed austenite.
The effects of austenite deformation stored enerey and austenite grain boundary en-
ergy change on the incubation time have been theoretically calculated. The calcula-
ted result seems to be consistent with a rule of experimental data that the austenite
deformation stored energy and the change of austenite grain boundary energy are
the nature of austenite deformation affecting upon the ferrite nucleation.
