Effect of Heat Treatment on Function of Ware-resistant Alloy Cast Iron
The influence of austenitizing temperature and time,tempering temperature and time,and so on heat treatment process parameters on microstructure and performance of ware-resistant alloy cast iron was investigate.The results show that,the microstructure is tempered martensite+ledebrite+some massive carbide after oil quenching at 880 ℃×40 min and tempering at 200 ℃×50 min,HRC≥53 HRC,impact toughness and wear resistantance is good.
