    摘要: A method of inspecting a repaired metal alloy part to analyze a microstructure of the metal part includes placing a replicating material on a surface of the metal part to create an inverted replica of the microstructure. The replicating material is then removed from the surface. An image of the inverted replica on the replicating material is magnified in order to evaluate the microstructure for incipient melting and areas of boride concentration. This inspection method facilitates that evaluation without causing any destruction to the metal part.

    摘要: An airfoil core has a frame formed of passage forming elements supporting a pair of spanwisely extending passage forming elements within the frame. The pair of passage forming elements has at least one plurality of hole forming elements extending chordwisely therefrom and supported in part by at least one of the pair of passage forming elements to increase the durability of the core. In one embodiment, the core includes a trailing edge region framed by spanwisely and chordwisely extending elements.

    摘要: A method of joining a microwave transparent component 36 to a host component 34 or 18 includes the steps of applying a Titanium-Tungsten (TiW) coating 44 to the microwave transparent component, applying a metal layer 46 over the TiW coating and brazing the microwave transparent component to the host. In a more detailed embodiment, the microwave transparent component is a ceramic component and the host component is a nonceramic component. In an even more detailed embodiment, the nonceramic component is made of a nickel base alloy and the metal layer is a nickel plating. A turbine engine component comprising a microwave nontransparent host 34 or 18 and a microwave transparent window 36 brazed to the host is also described.
