Abstract
There is provided a method for fabricating a dual alloy structure that may in turn be machined to fabricate a rotary component such as an impeller for use in a gas turbine engine. The method provides a first titanium alloy and a second titanium alloy. The first titanium alloy displays characteristics, such as high strength, suitable for application in the bore area of an impeller. The second titanium alloy displays characteristics, such as high temperature creep resistance, suitable for use in the outer radial area of an impeller. A bore subelement is fabricated from the first titanium alloy. A body subelement is fabricated from the second titanium alloy. The bore subelement and body subelement are joined by inertia welding at a common welding surface. Each subelement and/or the resulting welded structure is heat treated to achieve a desired microstructure.
