摘要
The disclosed invention specifies: 1) a metal or alloy with specific characteristics of its Deformation-induced Volumetric Microstructural Imperfections (DIVMI), 2) a method to measure these imperfections, and 3) a method to control these imperfections in a way that enhances one or more of strength, ductility, and the high cycle fatigue endurance limit of metals and alloys. The invention recognizes that all deformation-processed metals or alloys contain DIVMI and that through Severe Plastic Deformation processing one can minimize the characteristics of DIVMI that limit mechanical properties. Application of the methods to measure and control imperfections allows one to produce metals and alloys with strengths approaching the theoretical limit of strength.
