Zusammenfassung:	1436449 Nickel-base superalloys UNITED AIRCRAFT CORP 15 Oct 1973 [16 Oct 1972] 47980/73 Heading C7A A wrought superalloy article is formed from an alloy consisting by weight of:- the balance nickel. This alloy is solution heattreated at around 1121C, oil quenched, stabilized first at 871C and then at 982C and precipitation heat treated at 649C and 760C. The resulting article contains 50 to 60 volume % of a gamma prime intermetallic phase and is particularly suited for gas turbine components e.g. discs.
