Enhanced strength and ductility of rapid cooling friction stir welded ultralight Mg–14Li–1Al alloy joint

Ultralight Mg–14Li–1Al alloy sheets were subjected to conventional friction stir welding (FSW) and rapid cooling FSW (RCFSW) for comparative study. Compared with decreasing the rotation rate, the use of coolant significantly improved the thermal cycle and inhibited the grain coarsening. The RCFSW600...
