摘要

通过改变铝/ 镁搅拌摩擦焊接下压力，对6061–T6 铝合金和AZ31 镁合金板材进行对接焊，表征了接头宏微观组织结构，研究了组织结构与接头性能的关系。研究结果表明：当下压力为28kN 时，得到最高168MPa 的接头强度，此时铝/ 镁界面处金属间化合物层最薄，同时剧烈混合区内未出现无规则形貌的金属间化合物；随着下压力的增大，接头的力学性能呈现降低的趋势；下压力增大，使得搅拌头与待焊材料的摩擦产热升高，提高了焊接过程的热输入，使得铝/ 镁界面靠近底部金属间化合物层变厚且剧烈混合区内出现多相共存的混杂结构，同时界面偏上部出现形似孔洞的缺陷，降低接头性能。

Abstract

The influence of microstructure on the mechanical properties of 6061-T6 aluminum alloy and AZ31 magnesium alloy FSW joints was studied by changing Z-axial force. The results show that

when the Z-axial force is 28kN

the ultimate tensile strength of Al/Mg joints can reach 168MPa. The intermetallic compound layer at the interface is the thinnest

and there are no irregular intermetallic compounds in the severely deformed zone; The mechanical properties of the joints decrease with the increase of Z-axial force. With the increase of Z-axial force

the heat input in the welding process increases

resulting in thickening of intermetallic compound layer at the interface

the irregular structure appears in severely deformed zone and the hole-like defect appears at the upper part of the interface

which reduce the strength of the joints.
