摘要	Gradient structured metallic materials are attracting increasing attention because of their excellent properties. However, with existing manufacturing techniques, most reported gradient structures are limited to the near- surface regions or sample-level. Approaches are needed to prepare large metallic workpieces with throughout gradient microstructures for engineering applications. This work utilizes the characteristics of non-uniform deformation along the thickness direction of power spinning to manufacture high-Mn steel tubes with gradient nanotwins structures. The composition of high-Mn austenitic steel was carefully designed to make the twinning behavior sensitive to changes in strain. Specifically, the twin probability increases from 0.13 % in the innermost layer to 0.49 % in the outermost layer and the corresponding average twin boundary spacing decreases from 154.5 nm to 47.3 nm. The density of nanotwins presents a gradient, while the grain size and geometrically necessary dislocation density are nearly unchanged. A gradient distribution of hardness is obtained along the thickness direction of the tube with the gradient nanotwin structures. The hardness continuously increases from 3.32 GPa to 5.45 GPa distributed over a wall thickness of 8.5 mm. This work proposed a potential way combining material designing and power spinning for manufacturing large rod/tube-liked workpieces with throughout gradient nanotwins.
