High-strength mechanical and structural components, and methods of making high-strength components |
摘要 |
The invention includes components comprising an alloy containing a base metal and less than or equal to 30% alloying elements. The material has a grain size of less than or equal to about 30 microns and an absence of voids and inclusions of a size greater than 1 micron. The components have a yield strength at least 50% greater than the identical alloy composition in the 0 temper condition. Where the material is heat treatable, the yield strength is at least 10% greater than the identical composition in the T6 temper condition. The invention includes a method of producing components by casting and initial treatment to form a billet. The billet is subjected to equal channel angular extrusion and subsequent annealing at a temperature of less than or equal to 0.85 times the minimum temperature for inducing growth of submicron grains to over 1 micron.
