Abstract

Abstract

Hot deformation behaviors of pure iron and two kinds of low carbon steels with different pearlite contents were investigated by hot uniaxial compression using a Gleeble 1500 hot simulation testing machine at a deformation temperature of 700℃ and strain rates of 10 to 0.001 s^-1. The results indicate that pearlite has an important effect on the behavior of dynamic recrystallization of ferrite, that is, the increase of pearlite content promotes the dynamic recrystallization process of ferrite and broadens the range of strain rate in which this process can occur.
