<p>A process and an alloy are proved for producing high strength material having good ductility to provide a high strength, corrosion resistant alloy including the steps of (1) preparing a body of material having a composition consisting essentially of by weight, about 13% to 18% chromium, about 13% to 18% molybdenum, less than 0.01% carbon, less than about 6% iron, less than about 1.25% cobalt, less than about 4% tungsten, less than 0.5% aluminum, less than 1% manganese, less than 0.5% silicon, and the balance nickel with usual transient metals and impurities in ordinary amounts, and (2) thereafter aging said body at a temperature in the range about 900.degree. and 1100.degree.F to effect an A2B ordering reaction in the composition, the engineering properties of these alloys are particularly useful where a combination of high strength, ductility and corrosion resistance is essential, such as shafts in centrifuges, marine shafts, propulsion components and the like.</p> |
