Metallography in Detail

Metallography is a powerful technique used to examine the microstructural characteristics of metallic materials. By preparing and analyzing polished and etched samples under a microscope, engineers can assess grain structure, phase composition, inclusions, weld quality, heat treatment effects, and signs of fatigue or failure. This insight is essential for determining whether a material meets required specifications or has been properly processed for its intended application.

At 2R Inspection, we provide comprehensive metallographic analysis using both optical microscopy (OM) and scanning electron microscopy (SEM). Our services cover a wide range of applications, including weld evaluation, failure investigation, quality audits, and process verification. We prepare specimens with high-precision grinding, polishing, and etching techniques, and evaluate parameters such as grain size (per ASTM E112), microhardness profiles, intergranular corrosion, decarburization, and inclusion content (per ASTM E45).

Our metallurgical reports are fully documented, interpreted by certified professionals, and tailored to support client needs in industries such as aerospace, oil & gas, automotive, and manufacturing. With 2R Inspection, metallography becomes more than a microscope image — it becomes a window into the integrity and performance of your materials.
