结果表明:10Ni5CrMoV钢第一次淬火加热温度高于1200℃后晶粒急剧长大;二次淬火加热温度稍高于Ac3时,存在明显的组织遗传性,随二次淬火加热温度的升高,组织遗传性逐步消除,当淬火加热温度为810℃时组织遗传性开始消除;加热温度为960℃时发生再结晶,晶粒得到细化,组织遗传性完全消除,当加热温度高于970℃时细化的奥氏体晶粒开始长大。
The results indicated that fatigue fracture of the wire rope resulted from the secondary quenching caused by abnormal gliding friction of its surface.
