Metallographic examination is a fundamental technique for evaluating the microstructure, phase distribution, grain structure, inclusions, defects, and heat-treatment condition of metallic materials and alloys.
By examining a properly prepared metal specimen under optical or electron microscopy, metallographic analysis can reveal structural characteristics that are not visible during conventional visual inspection or mechanical testing. The results can be used to assess material quality, verify manufacturing processes, investigate failures, and support research and development.
Our metallographic examination services are available for a wide range of ferrous and non-ferrous metals, alloys, components, welds, castings, forgings, and advanced materials.
Metallographic analysis can provide information about a broad range of material characteristics, including: Grain size and grain morphology, Grain boundaries ,Phase distribution,
Microstructural constituents, Inclusion content and morphology , Porosity Cracks and microcracks ,Voids and shrinkage defects , Segregation, Decarburization, Carburization, Oxide layers, Surface defects, Heat-treatment condition, Welding microstructure, Coating and interface conditions, Corrosion-related microstructural changes, Manufacturing-related defects
