The inner stress produced by quick cooling during quenching is the basic reason of formation of quench-distortion of parts. 摘要淬火過(guò)程中的快速冷卻在工件內部產(chǎn)生的內應力是導致淬火變形的根本原因。
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. 根據淬火介質(zhì)冷卻特性曲線(xiàn)上的幾個(gè)特性值，選擇淬火介質(zhì)來(lái)預測鋼淬硬能力和淬火變形開(kāi)裂傾向，對提高零件質(zhì)量有重要的實(shí)際意義。
