Description

Ultrafine grained test pieces of aluminium, copper and steel produced by the accumulative roll bonding process were friction stir butt welded at various revolutionary pitches, and the microstructures and mechanical properties (tensile strength, Vickers hardness profiles) of the joints were evaluated. The materials used were 1050-O aluminium and oxygen-free copper (both 2 mm thickness, welded by SKD61 tool) and interstitial-free steel (1.6 mm thickness, welded by WC tool). TIG welding was also performed for comparison. The adverse effect of abnormal grain growth in the HAZ on the strength of friction stir welded copper joints is reported.
