Mechanical surface treatments

The use of components at a high temperature requires knowledge of the mechanical behavior of the materials used under these conditions. High-temperature deformation includes processes such as creep, relaxation, cyclic deformation (LCF, HCF), thermomechanical fatigue (TMF), and combined loading. High-temperature materials such as high-temperature steels and cast irons, Ni- and Co-based alloys, refractory alloys, intermetallic alloys, precious metal alloys, or composites are dealt with, but also protective coatings. In addition to mechanical characterization and the further development of the necessary testing technology, the Working Group deals with topics such as the influence of microstructure on mechanical behavior, microstructural stability, high-temperature corrosion, damage behavior and development, modeling of microstructural changes, and their influence on mechanical properties, and lifetime prediction.
