Abstract
572,779. Alloys; annealing. MOND NICKEL CO., Ltd. (International Nickel Co., Inc.). April 9, 1942, No. 5344/43. Divided out of 572,861. [Classes 72 and 82 (i)] An age-hardenable alloy containing over 10 per cent and usually 50 per cent or more of cobalt, and which may contain also up to 85 per cent of nickel, up to 10 per cent of manganese, up to a total of 45 per cent of chromium, copper, and iron, and up to 5 per cent of other elements, contains also aluminium with or without silicon or titanium or both, the cobalt plus nickel content being at least 45 per cent, and its ratio to the content of aluminium plus silicon plus twice the square root of the titanium being between 11 and 20 to 1, preferably between 13 and 17 to 1. The preferred alloys are copperfree and contain less than 25 per cent of chromium. Up to 1 per cent of carbon may be present. The alloys may be softened by quenching or rapidly cooling from over 1500‹ F. They may then be deformed cold, machined, and hardened by reheating to 1100-1500‹ F. for up to 24 hours and cooling slowly. Cold working may be applied before or after the agehardening.
