Metallographic testing is the fine examination of the structure of your sample at the macro-and-microscopic level.
The careful preparation of your sample by our material testers is crucial. Once a representative sample has been chosen, there are five preparation processes, carried out by hand: sectioning, mounting, grinding, polishing, and etching, which reveals the grain structure, including any surface defects.
Testing aims to evaluate the extent of decarburisation, the grain size, intergranular corrosion, inclusion content, the volume fraction of various phases, and identify the microstructures present in your sample, which significantly govern your material's mechanical properties like strength, toughness, and ductility.
