    摘要： 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.

    摘要： A shroud is provided for separating an air turbine starter housing from a turbine wheel. The shroud comprises a ring and a bumper. The ring is configured to be disposed between the turbine wheel and the housing and has an outer peripheral surface and an inner peripheral surface that defines a flow channel. The bumper is coupled to and extends radially inwardly from the ring inner peripheral surface and defines a bumper section of the ring flow channel. At least a portion of the bumper section has a cross-sectional flow area that is less than another cross sectional flow area of the ring flow channel.

    摘要： A flange protector for use with flanged pipe, pressure vessels and the like, having a peripheral flange with an outer peripheral surface and a central opening for the pipe or vessel and having holes in the flange for receiving bolts. The flange protector comprises a sheet-form plastic cover member with a dished central portion fitted into the central opening of the flange and a portion extending radially outward to cover the flange and the holes therein and an edge portion extending normal thereto to cover at least part of the peripheral surface of the flange. The radially extending cover portion is secured to the flange by the flange holes. The flange is a female flange with holes therein, the cover member radially extending portion has indentations or hollow protrusions fitting into each of the flange holes, each having an aperture with fasteners positioned therein extending into the flange holes to secure the cover member in place.
