Identification of deformation and damage mechanisms

© Fraunhofer IWM

Thermal and mechanical loading can lead to the transcrystalline and intercrystalline cracks and creep pores forming and growing. Oxidation and corrosion processes can also damage the material and change the microstructure to such an extent that the mechanical properties are significantly altered. When developing material models and designing components, it is therefore important to understand which deformation and damage mechanisms dominate during operation and how the mechanisms interact.
