Metallographic replication is a non-destructive sampling procedure which records and preserves the topography of a metallograhic specimen as a negative relief on an optical film. The technique is performed on the surface of a component in-situ to evaluate the microstructure and other surface features in lieu of physically removing material for laboratory evaluations. Metallograhic replication is a critical non-destructive method for assessment of in-service material, as some damage mechanisms are time dependent and temperature dependent, and evaluating the microstructure can detect critical defects or degradation of material before catastrophic failures occur. The microstructural replica can be examined using a light microscope or scanning electron microscope.
