    摘要: A gamma prime nickel-base superalloy and components formed therefrom that exhibit improved high-temperature dwell capabilities, including creep and hold time fatigue crack growth behavior. A particular example of a component is a powder metallurgy turbine disk of a gas turbine engine. The gamma-prime nickel-base superalloy contains, by weight, 18.0 to 30.0% cobalt, 11.4 to 16.0% chromium, up to 6.0% tantalum, 2.5 to 3.5% aluminum, 2.5 to 4.0% titanium, 5.5 to 7.5% molybdenum, up to 2.0% niobium, up to 2.0% hafnium, 0.04 to 0.20% carbon, 0.01 to 0.05% boron, 0.03 to 0.09% zirconium, the balance essentially nickel and impurities, wherein the titanium:aluminum weight ratio is 0.71 to 1.60.

    摘要: A system, in certain embodiments, includes a backing plate, a tungsten-based member disposed along the backing plate, wherein the tungsten-based member defines a welding work surface, and the tungsten-based member comprises curved grooves configured to secure the tungsten-based member to the backing plate. The system also includes a drive. The system includes a pin tool movable by the drive to create friction along one or more workpieces disposed on the welding work surface, wherein the frictional heating and mechanical stirring is configured to create a stir weld along the one or more workpieces. The system, in some embodiments, also may include a backing plate comprising liquid passages and gas passages and a tungsten-based member disposed along the backing plate, wherein the tungsten-based member defines a welding work surface.
