Introduction Strength and ductility are two conflicted factors of materials.
However, elicited by the structures of ancient animals and plants, additional the scale of fishes [1], the metal materials by means of treatment may be not only hard but also compliant as well as these scales.
As well known, surface mechanical attrition treatment (SMAT) [2] is generally used to enhance the strength by means of severe plastic deformation without changing the chemical components of materials.
