Outline
The hot deformation behavior of 25Mn-7Al-1C steel was investigated through single-pass hot compression tests in the range of 9 00~1 150 °C for temperature and 0.01~10 s-1 for strain rate. The constitutive equation and hot processing map of the tested steel were established. The results showed that the hot deformation activation energy of the steel was 447.5 kJ/mol, and the degree of dynamic recrystallization changed under different experimental conditions. Through synergistic analysis of dynamic recrystallization behavior and the hot processing map, hot working parameters with low temperature and high strain rate could enhance the impact toughness of the low-density steel. The optimal rolling process parameters for 25Mn-7Al-1C steel were confirmed as deformation temperature of 1 000~1 100 °C and strain rate of 0.01~1 s-1.
