Werkstoffcharakteristik

Werkstoffcharakteristik, also known as material characterization, refers to the systematic analysis of the properties and behavior of materials. The purpose is to determine characteristics such as mechanical, thermal, electrical, chemical, and microstructural attributes that define a material’s performance in specific applications. By comparing these properties against design requirements, engineers can select suitable materials and predict potential failure modes.

Key techniques used in Werkstoffcharakteristik include tensile, compression, and hardness testing to assess mechanical strength; differential scanning calorimetry and thermogravimetric analysis for thermal properties; and electrical conductivity measurements for electronic applications. Microstructural analysis, often performed by optical microscopy, scanning electron microscopy, or X‑ray diffraction, provides insight into grain size, phase distribution, and defect structures that influence material behavior.

The data derived from material characterization feed into computational models, informing finite element analysis and failure prediction tools. Standards such as ISO 788-2 and ASTM E8 guide the reproducibility and reliability of these tests. Furthermore, advanced techniques like nanoindentation, electron backscatter diffraction, and synchrotron imaging are increasingly employed to capture nanoscale phenomena.

In industry, Werkstoffcharakteristik underpins quality control, process optimization, and research & development across aerospace, automotive, biomedical, and energy sectors. Continuous improvement in testing methods and data integration enhances material selection, leading to safer, more efficient, and cost‑effective products.
