Study on High Temperature Mechanical Properties of Bearing Steel GCr15
Using Gleeble-3500 thermal simulation testing machine, the high-temperature mechanical properties of GCr15 Bearing steel was tested. The zero plastic temperature (ZPT) and zero strength temperature (ZST) were measured, so the optimum plastic temperature range and brittle temperature range were fond. The appearances of fracture at different temperature were analyzed by using scanning electronic microscope, and the fracture mechanism at different temperature area of the steel was discussed. which was thought as the theoretical basis for establishing the secondary cooling zone system of continuous casting.
