【 摘 要 】

The high temperature rheological curves of GCr15 bearing steel at different temperatures and strain rates were studied by MMS-300 thermal simulator. The dynamic recrystallization behaviour of GCr15 steel was analyzed with metallographic microscope. The dynamic recrystallization behavior of GCr15 steel was analyzed by combining metallographic microscope. The effects of austenitizing temperature, deformation amount, and strain rate on the dynamic recrystallization of tested steel were systematically studied. Based on this, the equation of hot working is established, and it is pointed out that the activation energy of hot deformation of GCr15 bearing steel is 291.35 kJ/mol.
