Metallography

Metallography is the study and analysis of the microstructure of metals and alloys using various microscopic techniques. It provides critical information about grain size, phases, inclusions, heat treatment effects, and material processing history. Metallography plays an important role in quality control, failure analysis, and research & development.

Types of Metallography:

• Macroscopic Examination: Low magnification study of etched or polished samples to reveal weld quality, grain flow, and defects.
• Microscopic Examination: Optical and electron microscopy to study fine details such as grain boundaries, inclusions, and phase distributions.
• Quantitative Metallography: Measurement of grain size, volume fraction, and inclusion rating as per ASTM and ISO standards.

Applications of Metallography:

• Failure investigation and root cause analysis
• Verification of heat treatment and material processing
• Assessment of welds, castings, and forgings
• Material characterization in R&D and production
• Ensuring compliance with ASTM E3, ASTM E112, ASTM E407, and ISO standards

We provide accurate Metallography services including sample preparation, polishing, etching, and detailed microscopic examination. Our reports support industries such as Oil & Gas, Power Generation, Manufacturing, Aerospace, Automotive, and Research Institutions with precise microstructural evaluation.
