EFFECT OF AUSTENITE DEFORMATION ON NUCLEATION KINETICS AND GROWTH KINETICS OF FERRITE
奥氏体形变对铁素体形核动力学及生长动力学的影响~*

The metallographic examination method was used to measure thenucleation kinetics and growth kinetics of ferrite formed at deformed austentite grainboundary.The nucleation kinetics equation for ferrite under austenite deformation was de-rived based on the classical heterogeneous nucleation theory,and the factors affectingnucleation kinetics were also discussed.The growth of ferrite nucleated at deformedaustenite grain boundary has certain direction.The reason for this phenomenon was pre-liminary explained.
