The numerical simulation of GCr15 YRT ring during quenching and deep cryogenic treatment

摘要

The temperature-microstructure-stress/strain coupling model of YRT inner ring in the process of oil quenching and deep cryogenic treatment (DCT) were established to study the change rule of cooling process, microstructure evolution and residual stress distribution in the process of oil quenching and DCT. The results provided the theoretical guidance for heat treatment process of YRT inner ring.
