摘　　要：对车桥用管XCQ16-1进行热处理后,发现管体存在组织异常、晶粒粗大和硬度不均匀等问题,经过分析,得出淬火工艺、回火工艺参数设置不当、及淬火介质的冷却能力偏低是导致上述问题产生的根本原因,同时也提出了相应的改进方案。Abnormal structure, coarse grain and nonuniform hardness of XCQ16 - 1 vehicle - bridge pipe are discovered after the heat treatment to it. The analysis shows that improper parameters for quenching and tempering, as well as lower cooling capacity of hardening media are the root causes. Moreover,appropriate measures are provided.
