Identification and modeling of fatigue damage mechanisms in Al-Si-Mg cast alloys under fatigue loading at high and very high number of cycles



The adaptability and the development of aluminum casting alloys for highly stressed components in mechanical engineering, automotive and energy technology requires reliable and quantitative knowledge of the context between the material microstructure and the associated fatigue properties. This research project will modulate the microstructural parameters and fatigue strength, based on specific solidified model alloys and commercial material samples of the system Al-Si-Mg. It will also enable the identification of fatigue damage mechanisms at the microstructural level and lead to a proper implementation of these mechanisms in a physically-based short crack model.

Duration: 2016 until 2020
