Procedures for preparing metallic specimens for submission to optical microscopy

Abstract

Microscopy analyzes are very important for metallography, they serve to reveal the microstructural constituents, the distribution of present phases and other important properties to characterize the materials. It is important that the specimens follow a rigorous preparation process to ensure that they are free from defects that could compromise the results of the characterization. The work presents the stages of preparation of specimens for optical microscopy. Works related to the research proposal were analyzed in literature texts and thus it was possible to identify the most common and effective practices in the preparation phase of metallic samples.
