Metallography
Structure and properties of Samples
Metallurgical Testing typically uses microscopy to provide important information about the structure and properties of metal and alloy samples which can then be correlated to processes such as heat treatment, rolling and many more to establish its effectiveness. These services are also called Metallography Evaluation, Metallographic Examination, and Metallurgical Analysis.

Testing
A typical metallographic examination consists of cutting, machining, mounting, grinding, polishing, and chemical etching to reveal the materials matrix microstructure. Subsequently, the sample is examined under an optical microscope or a scanning electron microscope depending on the application and client’s requirements.
Microscopic examinations may include:
- Microstructure
- Carburization & Decarburization*
- Grain Size (ASTM E112)
- Metallurgical Analysis Inclusion Rating (ASTM E45)*
- Plating/Coating Thickness*
- Carbide Precipitation*
- Case hardening*
- Ferrite by Point Count (ASTM E562)
- Intergranular Attack & Oxidation*
- Alpha Case - Titanium alloys*
- Intergranular Corrosion (ASTM A262)
- Sensitization*
- Surface Contamination*
- Nodularity, Nodule Count*
-
Eutectic Melting*
