Heat treatment for load-adjusted material properties of tailored forming components (A02)

• Subject Area: Mechanical Properties of Metallic Materials and their Microstructural Origins
• Term: since 2015
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 252662854

In order to positively influence the fatigue and alternating deformation behaviour in the hybrid materials considered within the framework of the Collaborative Research Centre, heat treatment strategies are adapted to the forming processes. Combining the strategies from the 1st and 2nd funding period with a concept for inductive solution annealing, a holistic heat treatment for the hybrid shafts made of steel and aluminium is developed. Additionally, the crack growth behaviour at the joining zones of steel-aluminium compounds is investigated.
