摘要: Abstract During reciprocating sliding of the Cu and Cu–Al alloys, we found that characteristics subsurface morphological patterns are intimately linked to dynamic recrystallization (DRX) structure generated by sliding. With decreasing DRX grain size, pattern changes from vortical laminar feature at about 0.5 μm. The motion is favorable for producing morphologically structure, while occurrence these processes rare under unidirectional Additionally, samples exhibit higher wear resistance than those sliding, which may facilitate development delaminating tribolayer. present results shed new insight into relationship between pattern, microstructure behavior materials different modes.
