EFFECT OF AUSTENITE DEFORMATION ON ISOTHERMAL NUCLEATION INCUBATION TIME OF PRO-EUTECTOID FERRITE
奥氏体形变对先共析铁素体等温形成孕育期的影响

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.
