  在试验所设计的焊接参数(焊速度恒为60 mm/min,搅拌头旋转速度分别为:400 r/min、600 r/min、800 r/min、1000 r/min、1200 r/min)下,对7050铝合金进行搅拌摩擦焊接(Friction Stir Welding,FSW)。之后借助MM-W1立式万能磨损试验机,采用销-盘式摩擦磨损方式,在室温干摩擦磨损及润滑摩擦磨损条件下,对比性地研究了7050铝合金FSW接头的摩擦磨损性能,探索了外加载荷、滑动速度以及润滑条件对其摩擦系数与磨损量的影响规律。

大型化工容器中存在大量的焊缝,在焊接残余应力及腐蚀介质的联合作用下,易产生垂直于焊缝的应力腐蚀裂纹,这些裂纹相互平行,且排列密集,裂纹尖端应力之间可能出现相互干涉问题,因而有必要对该类裂纹的应力强度因子复合问题进行研究,本文采用断裂力学的方法考虑平行裂纹间的相互影响,以确定合适的裂纹复合模型。
