Abstract: The disclosure describes example techniques and assemblies for joining a first component and a second component. The techniques may include positioning the first and second component adjacent to each other to define a joint region between adjacent portions of the first component and the second component. The techniques may also include inserting a solid retainer material into the joint region through an aperture in one of the first component or the second component to form a mechanical interlock between the first component and the second component and sealing the aperture to retain the solid retainer material within the joint region. The solid retainer material includes at least one of a metal, a metal alloy, or a ceramic.

Abstract: The disclosure describes example techniques and assemblies for joining a first component and a second component. The techniques may include positioning the first and second component adjacent to each other to define a joint region between adjacent portions of the first component and the second component, the joint region being coated with an adhesion resistant coating. The techniques may also include positioning a braze material in the joint region, heating the braze material to form an at least softened material, and cooling the at least softened material to form a mechanical interlock including the braze material in the joint region joining the first and second components. The braze material does not metallurgically bond to the joint surface.

Abstract: A method for fabricating a cast component with a cooling channel is provided. The method includes forming a shell mold over a pattern-ceramic matrix composite (CMC) elongated core arrangement to define a cavity in the shell mold. The pattern-CMC elongated core arrangement includes a pattern-forming material with a CMC elongated core disposed therein. The pattern-forming material in the cavity is replaced with metal via a casting process to form the cast component with the CMC elongated core disposed therein defining the cooling channel. The CMC elongated core is removed from the cast component to open the cooling channel for fluid communication.
