【 摘 要 】

The double-pass hot compression tests were carried out by MMS-300 thermal simulator. The effects of deformation temperature, deformation amount, strain rate, and austenite grain size on sub-dynamic recrystallization and static recrystallization of GCr15 bearing steel were studied systematically. Based on this, the microstructure controlling of invested steel wire rods during rolling was discussed in this paper, which can provide a basis for the reasonable determination of heating and deformation in the actual production process.
