Abstract
Heat treatment of an Alloy 282 which has been subjected to an initial solution annealing followed by cooling can be heat treated by heating the Alloy 282 to a temperature between 954° C. and 1010° C. until the gamma prime (γ') phase is sufficiently dissolved, and cooling the Alloy 282 to a temperature a sufficiently low temperature, and at a sufficiently high cooling rate, to suppress gamma prime precipitation. A component such as a turbine exhaust case and a gas turbine engine made of said alloy can be heat treated in the above manner.
