MaterialAusschnitt

MaterialAusschnitt is a specimen or cut-out piece removed from a larger material sample for examination. It is used to study the material’s microstructure, composition, mechanical properties and manufacturing quality. In metallography and materials science, a MaterialAusschnitt serves to evaluate grain structure, phase distribution, inclusions, porosity and surface finish. The selection aims to reflect the characteristics of the original material while accounting for regional variability within the part.

Preparation involves selecting a suitable location, cutting or sawing the piece, mounting it in resin if needed, and then grinding and polishing to expose a smooth surface for microscopy. For metals, etching with appropriate reagents reveals microstructural features; for polymers or composites, different preparation steps may be required to preserve internal structure. The size and shape depend on the analysis method and equipment.

Analytical work on a MaterialAusschnitt commonly includes optical microscopy and scanning electron microscopy, often with energy-dispersive X-ray spectroscopy or electron backscatter diffraction to assess composition and crystal orientation. Additional tests such as hardness measurements, X-ray diffraction or spectroscopic analyses may be performed on the same or separate cut-outs.

Documentation and storage are essential: each MaterialAusschnitt is labeled with location, material type or grade, date and test plan, and is archived for traceability. The term appears in German-language technical literature and industry, though alternatives such as Probestück or Schnittprobe are also used.
