Effects of Heat Treatment Process on Microstructure and
The grinding ball in cast state has poor mechanical properties. Mechanical properties of grinding ball significantly increase after heat treatment After heat treatment of 950 °C * 2 h oil quenching and 350 °C *2 h tempering, grinding ball gets the best comprehensive properties. Compared with cast state, impact toughness and Rockwell hardness are increased by 55% and 26% respectively. After
