    摘要: A non-destructive inspection method for detecting the presence of a contaminant that has alloyed with a metallic alloy of a part includes exposing the metallic alloy of the part to an extraction solution. The extraction solution extracts at least a portion of any of the contaminant that has alloyed with the metallic alloy. The extraction solution can then be analyzed to determine whether the solution includes any of the contaminant element, which indicates whether the part includes any of the contaminant element.

    摘要: A fixture for use in the final machining operation of the integral bladed rotor (IBR) of a gas turbine engine comprises a rigid ring (12) for surrounding the outer periphery of the IBR (14) and supporting tapered pins (16) that fit into the space between the blades (20) and then molded therein with a plaster or plastic medium for securing the unit to the IBR for enhancing its structural integrity. The method of finishing the airfoils of the IBR includes inserting the pins in alternate spaces and working half of the blade surfaces in the pinless spaces and then removing the pins and inserting pins in the previously worked spaces and then molding the pins in place. The other half of the bladed surface is then worked in the pinless spaces until the airfoils are finally contoured. The unit is removed and heated to melt the residual cast medium to produce the finished product.

    摘要: A dynamic compaction process comprises forming first and second preforms (16, 18). Forming each preform (16, 18) includes utilizing a container having an interior and an exterior. Filling the interior of the container with a powder material (20, 22); sealing the container; subjecting the exterior of the container to an instantaneous dynamic compaction, forming a solid powder metallurgy preform (16, 18) encased by the container. The container gets removed from each preform (16, 18). The process includes inserting the first and second preforms (16, 18) in another container (30) in a predefined pattern (31); the predefined pattern (31) aligns the first and second preforms (16, 18) creating an interface (28). The process includes inserting a backstop (46) against the predefined pattern (31) in this container (30); subjecting the exterior of this container (30) to an instantaneous dynamic compaction. The process includes bonding the first preform (16) and second preform (18) along the interface (28) to form a component precursor (10); and removing the container (30) from the precursor (10). Another step includes processing the precursor (10) into components (58).
