Metallography is the study of the microstructures of metallic materials. The properties of a material and its performance in a specific application depend on its microstructure. Rimkus utilizes numerous types and magnification of high-resolution optical and digital microscopes during the metallurgical examination process.

Analyses of microstructure in cross-sectioned samples help determine material properties, fracture propagation, corrosion pitting morphology, heat treatment, quality and thickness of plating and coating, grain size, overheat damage, material contamination, flaw characteristics, weld quality, manufacturing design flaws, and defect mechanisms.

The Rimkus Materials Testing and Investigation team has advanced training and knowledge in metallographic preparation procedures/processes, from sectioning and mounting the specimen through the grinding and polishing stages to proper selection and etching techniques of the tested material. Our expert laboratory staff is looked upon to provide metallurgical samples preparation techniques and their subsequent interpretations to clients from across the country.
