Distributions of grains and precipitates in gradient lamellae Al–Zn–Mg–Cu alloy by ultrasonic surface rolling processing

Improving surface properties can effectively expand the industrial application of aluminum alloys. In this study, a gradient nanostructured surface layer was successfully fabricated in an aged Al–Zn–Mg–Cu alloy by ultrasonic surface rolling processing (USRP). The microstructure and microhardness of...
