Abstract

Abstract: Effect of hot deformation on recrystallization behavior of niobium-bearing austenitic stainless steel 07Cr18Ni11Nb was investigated by thermal simulated compression test and pilot hot rolling test. The results show that the recrystallization degree of the steel increases with the increase of deformation temperature, deformation amount and holding time. When the deformation temperature and deformation amount are higher, the holding time required for recrystallization is shorter. The longer the holding time, the more obvious the growth of recrystallized grains. During rolling deformation, recrystallization is easier to occur at the quarter thickness of hot-rolled plate. With the increase of rolling temperature and deformation amount, fully recrystallized grains can be obtained at 1050 ℃ with rolling deformation of 25%.
