摘 要：Subjecting a workpiece to a surface treatment with severe impact loading is a novel severe plastic deformation procedure to fabricate gradient microstructures through the thickness and longitudinal direction.Mechanical performance is a function of twin density and the newly-formed grain size gradients.{1012}tensile twins created from processing without excessive grain refinement lead to strength enhancement with retained ductility.Creation of residual strain by a single impact results in a significant reduction in time and cost of the process.This paper investigates the effect of applying severe impact loading on mechanical and microstructural properties of magnesium for various impact velocities.
