Influence of hot deformation on dynamic recrystallization behavior of 300M steel: Rules and modeling

Dynamic recrystallization (DRX) is a major softening mechanism that impacts the microstructural properties of 300M steel during the forging of large parts. It refines the grains and eliminates defects from the material, and an in-depth analysis of the process is thus important. In the present study, the hot deformation behaviour of 300M steel was investigated by hot compression tests conducted at temperatures of 900–1150 °C and strain rates of...
