Abstract
The present invention is about the design and manufacturing method of constructing nano-structured lattices. The design of the four periodic two-dimensional lattices (hexagonal, triangulated, square and Kagome) is described; and the process of making nano-structured lattices is outlined in the present invention.
Claims8
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:
- R=(1−1/k)l/2
- where k is SMAT duration, and l is length of each of the bar members.
