초록
In the present work, dissimilar aluminum AA1050 alloy and oxygen-free copper Cu-OF were joined together by friction stirwelding. The joints were prepared under varying welding speeds at a tool offset of 1 mm towards aluminum alloy to facilitatebetter mixing of materials and to improve tool life. The morphology of the welded specimens was evaluated using SEM, andtheir mechanical properties were investigated using tensile testing, fractography, a micro-hardness survey, and wear analysis. The phases of the joint morphology were evaluated by EDS and the presence of intermetallics was analyzed by XRD analysis. Among the tested specimens, the joint fabricated at 220 mm/min exhibited the highest tensile strength of 106.4 MPa underductile fracture, and the maximum observed micro-hardness of 124 HV. The specimen welded at 220 mm/min demonstratedductile fracture in the weld nugget zone (WNZ). The wear analysis revealed that the 220 mm/min joint specimen had a lowerwear percentage (3.43%) than the other specimens (4.06% and 4.20%). The EDS morphology and XRD analysis of the 220mm/min joint revealed the presence of intermetallic compounds composed of thin layers of aluminum-copper compounds suchas Al2Cu and Al4Cu, which could improve the joint's mechanical performance.
