| 摘 要： | 以3mm厚2A14铝合金和TC4钛合金为试验材料,分别添加0.05mmZn和Ni箔片,研究了不同工艺参数下Zn和Ni对接头微观组织、力学性能的影响。试验结果表明：当添加中间层Zn时,在旋转速度为375r/min、焊接速度为75mm/min时,接头抗拉强度达到最大值237.3MPa,为铝合金母材拉伸强度的56.7%。同样参数下,添加中间层Ni后,能显著减少接头中脆性相TiAl3,接头抗拉强度最大值提高到285.3MPa,达到铝合金母材抗拉强度的68％,接头断裂方式呈脆性+韧性混合型断裂。

| Abstract: | The effects of process parameters, microstructure, mechanical properties of the joints, which were frabricated by friction stir welding (FSW) using 3mm 2A14 aluminium alloy and TC4 titanium alloy with a 0.05mm Zn and Ni ribbon as intermediate layer, were studied. The results indicate that the joint maximum tensile strength exceed to 237.3 MPa when the welding velocity, rotation speed are 75mm/min, 375 r/min, respectively, nearly 56.7% of the alluminum alloy. The joint maximum tensile strength reached 285.3 MPa at the same process parameters with add Zn as intermediate layer, nearly 68% of the alluminum alloy when add Ni as intermediate layer what can inhibit brittle phase TiAl3 , which the fracture mode is brittle/ductile fracture. |
