摘要
Abstract
The influence of quenching-tempering heat treatment,conventional austempering heat treatment and multi-stage austenitizing austempering heat treatment on the microstructure and property of high chromium cast iron grinding balls were comparative investigated.The results show that the impact toughness and impact fatigue resistance of the grinding balls are higher after austempering.Austempering heat treatment process is helpful for the high chromium cast iron grinding balls served in the large ball mill.关键词
