Abstract

A mathematical description of austenite structure after deformation in nonrecrystallization region is given. The essential characteristic of austenite grain, after recrystallization before deformation in the nonrecrystallization region is the effective nucleation area of austenite grain boundaries. Theoretical results are compared with experimental values for a C–Mn–Nb–V steel. The connection of austenite microstructure state before phase transformation and the ferrite microstructure after transformation is given too.
