Abstract
A steel having high strength and elongation is formed by subjecting an austenitic steel, having M s and M D below ambient temperature, 0À2-0À5% C plus N, and at least 0À5% of at least one element selected from Mo, Cr, Mn, V, Nb, Ta, W, to deformation above 650 F. but below its recrystallization temperature. In one example, stainless steel is heated at 2080 F. for one hour, cooled to 840 F. and rolled, e.g. 20%, 80%, after which it is quenched to room temperature. Alternatively the steel may be quenched from 2080 F. to room temperature, reheated to 840 F. and rolled 80% to form a steel having an elongation of 40% and a yield strength of 222,500 p.s.i. This steel may be further strained 15% at room temperature and finally heated at 840 F. for 30 minutes resulting in an elongation of 25% and a yield strength of 273,000 p.s.i. In another example, the steel is cooled after deformation to liquid nitrogen temperature, strained below ambient temperature and tempered above room temperature.
