Effects of Roller Expansion Parameters on Residual Stress and Fatigue Life of TA15

  • 摘要: 滚柱挤压强化是重要的表面处理方法,能够在材料内部形成稳定的残余应力,进而有效提高结构的疲劳性能。针对TA15钛合金开孔结构,滚柱挤压强化参数对残余应力及疲劳寿命的影响规律有待进一步研究。基于Johnson-Cook方程建立了TA15滚柱挤压过程仿真模型,揭示了不同挤压量和摩擦因数下,残余应力的产生、扩展及影响范围,探讨了挤压后孔壁材料在周向及轴向的变形规律;开展了TA15开孔结构疲劳寿命试验,对比研究了挤压强化后疲劳寿命的增益效果。
