The basics of materialography and metallography
Materialography plays an important role in modern science and engineering, and it is a cornerstone of quality control within the laboratory and production environments. Materialography covers most materials, including:
- Ceramography (ceramics)
- Metallography (metals)
- Plastography (polymers)
- Mineralogy (minerals)
Every material contains millions of microstructural features per cubic centimeter, which strongly influence the properties of the material. The goal of materialography is to analyze the true structure of the metal, alloy or other material through the optical examination of its microstructure.
Microstructure is characterized through the size, shape, arrangement, amount, type and orientation of phases within a material, as well as any defects in these phases.
