Abstract: We use GLEEBLE 3500 to study the relationship model of dynamic recrystallization, static recrystallization and deformation resistance of high-strength corrosion-resistant car body steel during thermal deformation. We found out strain rate and deformation temperature have some influences on the deformation resistance of high-strength corrosion-resistant steel, and formed a certain rule. We have established the deformation resistance model of high-strength corrosion-resistant steel and calculated the activation energy of dynamic recrystallization. The inf-luence of deformation temperature and track interval time on the stress-strain curve was studied through the two-pass compression experiment, and the softening rate under various deformation conditions was calculated. The results show that the deformation temperature and deformation rate have the most obvious influence on the compressive stress-strain curve of the high strength and corrosion resistant steel. The effect of deformation temperature and track interval time on the stress-strain curve of double-pass compression is obvious. As the deformation temperature increases and the interval between passes increases, the static recrystallization degree of high-strength corrosion-resistant steel increases, and the softening effect becomes more obvious.
