| 摘 要： | 对已开裂断线钳钳头的显微组织、化学成分和硬度进行了检测和分析。结果表明．开裂原因是由于高频淬火前粗大的显微组织和淬火时淬硬层过深．导致拉应力过大而引起。

| Abstract: | The microstructure, chemical composition and hardness of cracked jaws of wire clippers were detected and analyzed. The result shows that the coarse-grain microstructure before high frequency quenching and over-deep hardened case during hardening lead to too high tensile stress and cause the samples cracked. |

| Keywords: | wire clipper jaw high frequency quenching structural stress |
