Title of Paper:
TC4 钛合金激光深熔焊小孔形貌特征
Journal:
稀有金属材料与工程
Summary:
针对TC4 钛合金激光深熔焊接的特点,建立了适合小孔尺寸精度的微米级精细计算模型。结合TC4 钛合金材料属性,利用能量分布与小孔形貌特点相类似的高斯旋转曲面体热源进行加载,得到了随激光焊接工艺参数改变而变化的小孔形貌及瞬态温度分布特征。通过分析瞬态过程小孔前后沿、小孔径向以及小孔深度方向的特征尺寸及温度分布,得出了对TC4 钛合金激光焊接小孔形貌影响最大的工艺参数。通过分析各工艺参数的影响规律,提出了TC4 钛合金激光焊接得到最佳小孔形貌或温度分布的工艺参数取值范围。
