Metallographic tests are based on the examination of the natural surfaces or specially prepared metallographic specimens in order to define the structure, assess the quality or identify internal flaws in the material.
We provide:
Examination of a prepared surface of a sample’s cross-section carried out with the naked eye or under low magnification – no more than 30x. Its aim is:
Examination of a prepared surface of a sample’s cross-section carried out with the naked eye or under low magnification – no more than 30x. Its aim is:
- to detect discontinuities in the material such as fractures, overlapping, shrinkage cavities, blisters and non-metallic inclusions
- to assess other parameters of the material such as trace impurities (sulphate or phosphorus), size of grain, depth of hardening, texture direction and nature of fractures
