摘　　要：针对50CrMo4钢丝杆零件表面开裂的现象,对开裂试样进行了化学成分、金相、扫描电镜等分析。结果表明:50CrMo4钢丝杆的表面开裂是感应加热淬火温度过高产生的表面淬火开裂。The chemical composition test,metallography and scanning electron miccroscope were adopted to analyse the surface cracking on steel wire rod 50CrMo4.The results show that the surface cracking is the surface quenching cracking caused by higher induction heating quenching temperature.

关 键 词：50CrMo4钢 表面开裂 淬火开裂
