Abstract

High strength AA2219-T87, Al-Cu alloy of 6mm plates were friction stir welded. Microstructures, micro hardness values, tensile properties and corrosion analysis were studied in the welded condition. The stirred region of the welded specimen looked like a rectangular shape, with a weld flow arm moving towards the top surface of the welded plates on each side of the welded region. Presence of CuAl2 particles found to be large in size in the base material of 2219 when compared to those in the weld nugget. The welded region 2219-2219 showed better pitting and general corrosive resistance compared to the 2219 parent metal.

2219-T87搅拌摩擦焊接铝合金力学性能及抗点蚀性能研究

采用搅拌摩擦焊接高强度AA2219-T87、铝铜合金6mm板。研究了焊接条件下的显微组织、显微硬度值、拉伸性能和腐蚀分析。焊接试样的搅拌区呈矩形形状，焊接区两侧各有一个焊流臂向焊板顶面移动。与焊核相比，2219基材中存在较大的CuAl2颗粒。与2219母材相比，2219 ~ 2219焊接区具有更好的点蚀性和一般耐腐蚀性。
