研究了热处理工艺对高铬铸铁组织和性能的影响。结果表明，高温淬火，中温回火可以大大改善高铬铸铁的组织形态，显著提高其冲击韧性。并对热处理工艺的合理选择进行了分析讨论。
The effect of heat treatment on microstructure and properties of high chromium cast iron was studied. The results show that high temperature quenching, tempering at medium temperature can greatly improve the high chromium cast iron morphology and significantly improve its impact toughness. And the reasonable choice of heat treatment process is analyzed and discussed.
