Frequently Asked Questions
Common questions about metallography testing services
Metallography is the study of microstructure and macrostructure of metals and alloys to evaluate grain size, inclusions, weld quality, defects, and overall material characteristics using optical microscopy and image analysis.
Grain size directly affects strength, toughness, ductility, and fatigue resistance of metals. Finer grains generally provide better mechanical properties and performance.
Yes, we provide comprehensive weld profile checking, depth of penetration measurement, fusion zone analysis, and weld defect detection as per ASTM, AWS, and ISO standards.
Yes, we conduct detailed failure analysis, inclusion rating (ASTM E45), carburization/decarburization studies, defect characterization, and root cause identification.
Metallography is essential for automotive, aerospace, oil & gas, power generation, defense, manufacturing, and any industry requiring high-performance metal components.
We use Biovis MP 2000 Image Analysis Systems with optical microscopes providing 50x to 1000x magnification for detailed microstructural examination.
Standard metallography testing typically takes 3-5 business days depending on sample preparation requirements and analysis complexity. Expedited service is available upon request.
Yes, our reports include detailed findings, high-resolution micrographs, root cause analysis, and actionable recommendations from experienced metallurgical engineers.
