Study on the Thermal Deformation Behavior of Cu-P –Type Weathering Steel

摘要：

Using thermal simulator (Gleeble 1500D), the thermal deformation behavior of Cu-P weathering steel containing Cr, Ni, Mo under different deformation temperatures and strain rates was studied. The true stress-true strain curves at different thermal deformation conditions were got, and the thermal deformation equation was established. Then the microstructure features of the steel under different deformation temperatures and strain rates were analyzed when the true strains were same. The results show that with the same strains and strain rates, the higher the deformation temperature, the easier the recrystallization occurs, and the greater the size of the recrystallization grains. And with the same strains and deformation temperatures, the lower the strain rate, the easier the recrystallization occurs, and the greater the proportion and size of the recrystallization grains.
