Claim Text:
1. A method for fabricating a nano-structured lattice based on surface mechanical attrition treatment (SMAT), comprising: partly or completely treating a solid material by the SMAT; and cutting off one or more holes from the treated solid material to form a lattice comprising a plurality of bar members connected to each others by one or more nodes; wherein one or more of the bar members are partly or completely treated by the SMAT; wherein the lattice comprises a square lattice comprising the holes in square shape; wherein the treated bar members are partly treated at one or more end portions of the treated bar members within a circle around the node; and wherein the circle has a radius (R) calculated by: where k is SMAT duration, and l is length of each of the bar members.
