tempered sorbite

The results showed that tempered soft zone in harden zone case produced in process of discontinuous medium frequency induction hardening which has microstructure of tempered sorbite and low hardness and low fatigue limit were major reason to cause driven gear cracking.

结果表明，因中频淬火的不连续，使淬硬层出现了回火软区，组织为回火索氏体，降低了材料的硬度和疲劳极限，最终导致从动齿轮开裂。
