Metallurgical examination permits qualitative and quantitative description of the structure of metallic materials in order to determine the material properties.
To make the structure visible, the material needs to be ground, polished and usually etched. It is then examined either macroscopically (without aids or with a lens up to 10-fold magnification) or microscopically (optical microscope up to 1000-fold magnification or electron microscope up to 10 000-fold magnification).
This provides information on the manufacturing procedures applied, such as casting, welding, moulding, hardening or coating. In addition, material faults such as cracks, pores or inclusions become visible.
Metallography is also an important part of our damage analysis.
