AZ31 hot-rolled plates with gradient nano-grained surface were produced by surface mechanical attrition treatment (SMAT). The grain size was refined to nanoscale at the surface layer via twinning and dynamic recrystallization (DRX). The micro-hardness at the top layer had a 132% improvement and the...
