Metallography is a metal science discipline. The purpose is the qualitative and quantitative description of the structure of metallic materials with the help of microscopic methods. Due to the increasing number of composite materials and the emergence of new, further developed materials, the term “materialography” has also established itself, as it covers the entire spectrum of materials.
In-depth knowledge of materials science and their properties, or more specifially the processing of metals, is essential for our material testers and metallographers, in order to avoid errors in the preparation of the samples and the subsequent structural assessment.
We examine and evaluate a wide variety of metallic materials in order to solve material science tasks in the areas of development, quality assurance or damage analysis.
- Optical emission spectroscopy (OES analysis)
Spectral analysis to determine the chemical composition
- Structural examination in microsection
– Heat treatment condition
– Grain size determination
– Determination of porosity according to VW 50093, VW 6093
– Primary silicon crystal evaluation
– Edge decarburization
- Fracture analysis / crack investigation (forced fracture, fatigue fracture, brittle fracture, hydrogen embrittlement)
- Weld seam examination in the cut
- EDX analysis with SEM examination
- SEM line scan and mapping
