About Metallography

Metallography is the scientific study of the microstructures of metals, typically employing light microscopy for microstructural examination. It has long been known that the physical properties of materials, and hence, the microstructures of these materials are changed by their respective manufacturing processes. Our metallographic work involves the art and science of preparing relevant samples and interpreting these microstructural changes related to the specific manufacturing processes the material has been through.

To insure that the material will meet particular design criteria, the microstructures of many materials are examined against known validation standards throughout the manufacturing process and prior to end usage. Metallography is not only used for standardized quality control and/or process control techniques. It is also used for problem solving when combined with failure analysis and forensic engineering techniques. Light microscopy techniques can also be employed on composites, ceramics and polymers, and are often used to evaluate the microstructural characteristics of these materials as well.

Three-D Microscopy

Three-D microscopy is a new generation in optical microscopy. It combines the functions of a stereo microscope, metallurgical microscope, electron microscope, and a measuring microscope. Because it offers a large depth-of-field and advanced measurement capabilities, we utilize the Keyence VHX-5000. This versatile all-in-one digital microscope uses either manual or automatic intuitive operating parameters and provides a complete range of imaging and measurement capabilities with 360 degree visual representation from 1x to 5,000x magnification.

Mechanical, Fatigue & Simulated Service Testing

Mechanical testing is used to determine a material's strength by applying loads that pull, compress, impact, bend, or cycle the material. Along with Simulated Service Testing, these techniques can be used to determine the durability of materials or components, performance capability, or life expectancy in everyday applications. Types of testing we perform include:

Mechanical Testing Tools

Tensile Testing From -450?F To 1800?F (ASTM E8)
Charpy Impact (ASTM E23)
3 Pt & 4 Pt Bend (ASTM E290, ASME Section IX)
