the results show that nitrogen has remarkable influences on rolling contact fatigue life and plain strain fracture toughness, and little influences on wear resistance.
结果表明,含氮量对滚动接触疲劳寿命及平面应变断裂韧性具有很显着的影响,而对耐磨性影响很小。
the rolling contact fatigue life was found to be markedly related the subsurface crack propagation angle.
疲劳寿命与次表面裂纹扩展角之间存在着明显的对应关系。
a new explanation of reason why the rolling contact fatigue life can be prolonged by residual compressive stress and retained austenite was advanced.
并对残余压应力和残余奥氏体可以提高接触疲劳寿命的原因提出了新的解释。
