Abstract: A nickel base powder metallurgy superalloy gas turbine engine disk for a compressor or turbine. The wrought powder metallurgy gas turbine engine disk has desirable fatigue crack growth resistance and a superior balance of tensile, creep rupture and low cycle fatigue strength characteristics. In one embodiment the disk defines a segregation free homogenous structure.

Abstract: A family of gamma titanium aluminide alloys is provided which is based on the intermetallic compound TiAl and includes alloying additions which enable the alloys to exhibit both sufficient mechanical properties and environmental capabilities for use in high temperature applications associated with gas turbine and automotive engines. The preferred alloys have a nominal aluminum content of about 46 atomic percent and further include niobium at about three to about five atomic percent and tungsten at about one atomic percent nominally, so as to selectively enhance the oxidation resistance of the alloy. As species of the preferred alloy, alloying additions of vanadium, chromium and manganese can be included at levels of up to about two atomic percent to enhance the toughness and ductility of the preferred alloy at lower temperatures, such as those encountered during fabrication and during low temperature operations.
