Effect of Cold Rolling on Bonding Interface of C1020/A1050 Butt Joints by Friction Stir Welding

Abstract:

This study utilized friction stir welding for butt joining of A1050 and C1020 plates, investigating the effects of cold rolling and annealing on the structure of the bonding interface and the hardness of the materials. The experiments revealed successful joint formation with minimized copper dispersion in aluminum and the formation of intermetallic compounds. Cold rolling resulted in increased hardness without significant crack propagation along the bonding interface. Annealing effectively reduced the difference in hardness, indicating that copper recrystallizes earlier than aluminum.
