Investigations on the influences of surface topography and corrosion on the fatigue strength of steel/aluminum hybrid sheets produced by magnetic pulse welding

Magnetic pulse technology allows welding of hybrid components of steel and aluminum with low amount of thermal distortion and without temperature-induced microstructural changes. The aim of the project is the efficient characterization of the fatigue behavior and damage mechanisms of steel/aluminum-joints produced by magnetic pulse welding, which have not yet been properly researched, by means of combined load increase and constant amplitude testing procedure. The focus of the investigations is the determination of the influences of specifically adapted surface topographies and corrosion on the fatigue strength and damage propagation.

Duration: 2017 until 2019
