Softening during and after the hot deformation of the AISI 321 steel with respect to practical applications

Abstract

The softening processes during and after the hot deformation (850–1180 ‡C) in AISI 321 stainless steel were studied with respect to true strainsε D and true strain rates\(\dot \varepsilon _D \). The analysis of deformation curves indicates the occurrence of dynamic recrystallization for values of Zener-Hollomon parameterZ≈1015 s−1. The retardation of static recrystallization by fine Ti(N, C) precipitates is documented by microstructure studies and by variations of annealing conditions.
