ABSTRACT:
A method of producing high strength nanophase metal alloy powder by cryomilling metal powder under conditions which cause the formation of intrinsic nitrides, and of producing high strength metal articles by subjecting the nitrided cryomilled powder to thermo-mechanical processing. The intrinsic nitrides present within the alloy significantly reduce grain growth during thermo-mechanical processing, resulting in formed metal products of high strength and improved ductility.
