A thermo-mechanical treatment (TMT) at the temperature of maximum dynamic strain aging has been optimized and performed on quenched and tempered steel SAE4140H (German designation: 42CrMo4) in order to improve the fatigue limit in the high cycle fati

Intermetallic materials typically change their deformation behavior from brittle to ductile at a certain temperature called the Brittle-to-Ductile Transition Temperature (BDTT). This specific temperature can be determined by the Charpy impact, tensil

The comprehension of solute-induced phase transformations is crucial in a variety of research fields such as catalysis, memory switching or energy storage. We study solute-induced phase transformations on the model magnesium-hydrogen (Mg–H) system

Additive manufacturing (AM) of the maraging steel X3NiCoMoTi18-9-5 (or 18Ni300) is readily used for close contour cooling of complex forming dies or injection moulding dies, and can be used at long-term operating temperatures up to 400 °C. Therefore

In this study, the influence of rotary swaging induced cold work on long fatigue crack growth, threshold and opening behavior in the nickel-based superalloy Inconel 718 was investigated. Ambient temperature experiments were carried out using arc-shap

The investigation of cyclic crack propagation rates (CPR) for different loading ratios is very elaborate. A multiscale numerical approach to predict high cycle fatigue (HCF) strength for a ferritic-pearlitic steel has been modified to be applicable f

Metallic materials can exhibit creep or relaxation effects even at room temperature. For technical applications, this is typically not relevant because the effects are usually assumed to be small and therefore not relevant for the failure of componen
