Materialography/metallography is the elucidation and qualitative and quantitative description of the microstructure of metallic materials and composites using microscopic methods. It is used for quality assurance, loss event analysis, research and development.
The surface of previously ground and polished samples is etched to examine the microstructure. Only material defects such as cracks, pores or inclusions can be investigated without etching. Most etchants are compositions of various acids, acid solids or alkalis. MORPHISTO offers a wide range of common etchants in small and large containers for almost all applications.
