Abstract
Bimetallic Al/Ti-6Al-4V clad sheets were fabricated via a novel technical route, mainly by multi-pass friction stir lap welding method. Preliminary investigations on process principles, clad-sheet formability, bonding property, and interlayer structure evolutions were performed. The anti-oxidation performance of Al/Ti-6Al-4V specimens was particularly researched, considering our focus on the protection role of exterior Al-cladding. More fully Ti/Al inter-diffusion and phase-stratification occurred within the interlayer after oxidation test. The Ti/Al interlayer forming mechanisms by friction stir lap welding was elucidated.
