High performance nanostructured materials and methods of making the same

A nanostructured material having a tensile elastic yield strain of at least about 1% for the material and a ductility from at least about 1 to about 18 percent plastic strain-to-failure.

A method of making a nanostructured material comprising melting a metallic material into a liquid state, solidifying the material, deforming said metallic material wherein a plurality of dislocation cell structures are formed, annealing said metallic material at a temperature from about 0.3 to about 0.7 of its absolute melting temperature, and cooling said metallic material to produce nanostructured material having a tensile elastic yield strain of at least about 1% for the material and a ductility of at least about 1 percent plastic strain-to-failure.

Nanostructured magnetic materials, wherein the materials are cold-rolled and annealed at a temperature ranging from about 350 to about 705 degrees Celsius, have a room temperature yield strength from 1.2 GPa to more than 2.3 GPa, and tensile ductility from 1% to more than 18% plastic strain-to-failure;
