Effect of Oxide Array on the Fatigue Property of Friction Stir Welds
Scripta Materialia
Abstract
The fatigue behaviour of single-sided friction stir (FS) butt welds containing oxide array was investigated. The oxide array makes cracks initiate easily under fatigue loading, and has a deleterious effect on the fatigue properties of FS welds. The fatigue characteristic values of FS welds with oxide array have been decreased by 35% for 5083 welds and 55% for 2024 welds at 2 x 106 cycles. The fatigue lives of FS welds with oxide array were 20-40 times shorter for Al 5083 welds and 30-80 times shorter for Al 2024 welds than those of sound welds under the stress ratio R = 0.1.
