Materials Characterization and Testing

Intentionally destroying in a controlled process what others have created: IWS material and component testing researchers examine the material up to the smallest detail. In this process, the scientists evaluate material and component quality and suggest ways to optimize manufacturing processes. 

The competence field is a partner for external industrial customers and internal consultant for all technology fields of Fraunhofer IWS. Comprehensive material knowledge, years of experience in techniques and a wide range of available equipment and devices provide the basis for their research and engineering projects.
 

Materials characterization

The service portfolio includes the metallographic characterization and electron-microscopic analysis of materials and their compounds, from the macro to the nano scale. Characteristic properties are determined and strategies are derived in order to be able to design components according to material and operational demands. The scientists assess suitability, select materials, and optimize the component for the development and refinement of manufacturing technologies. In addition, they develop, evaluate and modify test methods. Failure and damage analyses are also part of the portfolio.


Materials Testing

Besides the classical mechanical properties, the team of Materials Testing investigates the fatigue behavior of materials at very high numbers of load cycles. Due to the existing high frequency testing machines, it is possible to carry out fatigue tests in the very high cycle fatigue regime (VHCF) within a reasonable time. In connection with the existing analytical equipment, fast and well-founded assessments of material conditions or process parameters can be performed. This short-term diagnostics facilitates the active support of material and component developments.

In correlation with Industry 4.0 and digitally supported added value, the validation of these processes is gaining in importance. For this reason many studies focus on the process – property correlation of materials. The competence field of materials characterization and testing develops and analyzes test-based validation processes for the digital twin and understands itself as bridge builder between product or process simulation and quality assurance.
