The inner stress produced by quick cooling during quenching is the basic reason of formation of quench-distortion of parts. 摘要淬火过程中的快速冷却在工件内部产生的内应力是导致淬火变形的根本原因。
Some specific values of cooling characteristics of quenchant can be used to forecast the steel hardening power, distortion and cracking susceptibility and select the quenchants. 根据淬火介质冷却特性曲线上的几个特性值,选择淬火介质来预测钢淬硬能力和淬火变形开裂倾向,对提高零件质量有重要的实际意义。
