ABSTRACT:
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.
