Metallography is the study of a materials microstructure. Analysis of a material’s metallographic microstructure aids in determining if the material has been processed correctly and is therefore a critical step for determining product reliability and/or for determining why a material failed. The basic steps for proper metallographic specimen preparation include: documentation, sectioning, mounting, rough grinding, fine grinding, polishing, etching and examination.
