异种铝合金搅拌摩擦焊接接头的微观组织与力学性能
MICROSTRUCTURE AND MECHANICAL PROPERTIES OF FRICTION STIR WELDING JOINT OF DISSIMILAR Al-ALLOYS
摘 要
采用搅拌摩擦焊方法对4 mm厚的5083铝合金与6082铝合金进行了焊接,对焊接接头的微观组织和力学性能进行了分析。结果表明,焊核区由细小的等轴再结晶组织构成,6082铝合金在前进侧的抗拉强度大于5083铝合金在前进侧的抗拉强度,正弯试验与背弯试验角度都达到180°。

Abstract
Dissimilar 5083-6082 Al-Alloys in 4 mm thickness were successfully friction stir welded. The metallographic observation demonstrates that the dynamic recrystallization occurred in the weld nugget,which consists of refined equiaxed grains. Mechanical tests demonstrate that the joint in which 6082 Al-Alloy was located on advancing side shows a higher tensile strength than that of 5083 Al-Alloy on advancing side;the angles upon face and root bend tests attains to 180°.
