Abstract

Abstract: A heat treatment process for improving carbide morphology of wear resistant high manganese steel was discussed. The results show that the morphology and distribution of precipitated carbides in this wear-resistant high manganese steel can be effectively improved by water toughening treatment combined with high pressure heat treatment and atmospheric pressure heat treatment. After water toughening treatment, the wear-resistant high manganese steel can obtain dispersed granular and short strip carbides after 5 GPa, high pressure heat treatment at 650 ℃ for 30 min and heat treatment at 750-800 ℃ for 60 min.

Key words: wear resistant high manganese steel, high pressure heat treatment, carbide morphology
