摘　　要：用非调质钢材料代替调质钢材料来制造发动机胀断连杆,可以省去一道热处理工序,从而利于节能环保,采用胀断技术代替传统的平切技术,有利于提高连杆的装配精度。对胀断连杆用KNF33MAM非调质钢的化学成分、低倍组织、显微组织、非金属夹杂物等方面进行分析,结果可为提高国内材料水平奠定理论基础。Using non quenched and tempered steel materials to replaced quenched and tempered steel materials to manufacture engine expanding and breaking connecting rods could save a heat treatment process, which was conducive to energy conservation and environmental protection. Using expanding and breaking technology to replaced traditional flat cutting technology was conducive to improving the assembly accuracy of connecting rods. The chemical composition, macrostructure, microstructure and non-metallic inclusion of KNF33MAM non quenched and tempered steel for expanding and breaking connecting rod were analyzed. The results could lay a theoretical foundation for improving the domestic material level.
