Metallography & Microscopy

Metallographic evaluation reveals a level of detail far beyond the eye can see. Using advanced preparation procedures and high powered microscope imaging systems, metallographic analysis is vital in determining why a part failed or even verifying that a particular material is processed correctly prior to service.

SMS Labs’ state of the art metallographic laboratory offers decades of experience analyzing the most complex industry alloys from ancient artifacts to aerospace super alloys.  Years of careful procedure development ensure that SMS sample preparation and evaluation are specific to alloy type, condition, and form.
