TION AND SIGNIFICANCE

WITHIN the last decade, ultrafine-grained (UFG) materials have received substantial interest owing to their combined high strength and ductility in comparison with conventional coarse-grained (CG) alloys.[1–6] Several methods have been proposed to produce these materials with grain sizes in the submicrometer (100 nm to 1 lm) and nanometer (
