I will present and discuss the microstructure, texture, and properties of gradient materials processed by surface mechanical attrition treatment (SMAT). Gradient structures are characterized with macroscopic systematic change of microstructures such as grain size, texture and defect density. Recently gradient structures with grain size gradient from nano-scale to micro-scale were introduced into metals by SMAT, producing excellent strength and ductility. The material with a gradient structure has a built-in mechanical incompatibility during the tensile deformation, which generate geometrically necessary dislocations and back stress. The effect of textural gradient is superimposed on the grain size gradient and need to be further studied by theoretical modeling. Materials with gradient structures represent an emerging academic field with many fundamental and engineering problems to be solved by researchers from the communities of materials science and materials mechanics.
