The results indicated that fatigue fracture of the wire rope resulted from the secondary quenching caused by abnormal gliding friction of its surface. 结果表明:钢丝绳表面不正常滑动摩擦造成表面二次淬火是疲劳开裂的原因;
The analysis of wearing condition of spindle pivot point after the formation of secondary quenching layer in grinding burn 精纺锭杆锭尖部分磨削二次淬火烧伤后磨损状态分析
The secondary hardness of the tested steels is increased with the contents of alloying elements such as Mo, V, Si and changed with quenching temperature to show two peaks. 随Mo、V和Si等合金元素含量升高钢的二次硬度升高,随淬火温度升高钢的二次硬度出现两次峰值。
