摘　　要：在模拟实际件冷度速度的基础上，着重研究了四种典型合金白口铸铁的强度、组织、耐磨性及磨损形貌，试验结果表明：以Ｍ７Ｃ３型加ＶＣ型碳化物的Ｍ２合金，其硬度高，碳化物分析均匀，耐磨性好。The hardness, microstructure, wear resistance and wear appearance of four typi- cal alloyed white casting irons were studied based on the simulation of cooling of practical part.The results showed that M2 with the carbides of M7C3 and VC had high hardness, well - distributedcarbides and high wear - resistance.
