摘要	The sliding wear resistance of Cu-2.2 wt.% Al alloy can be remarkably enhanced by controlling subsurface dynamic recrystallization (DRX) process. The wear volume decreases from 3.1 x 10(7) to 0.9 x 10(7) mu m(3) when the DRX grain size increases from 0.28 to 0.62 mu m induced by dynamic plastic deformation and subsequent annealing. The enhanced wear resistance stems from a wear mechanism transition from cracking and peeling-off of the fine-grained DRX layer to that of the topmost nanostructured mixing layer as DRX grains become coarser.
