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

为了对合作研究中心框架内考虑的混合材料的疲劳和交替变形行为产生积极影响，热处理策略应适应成形过程。将第一期和第二期资助的策略与感应固溶退火的概念相结合，开发了一种针对钢和铝制成的混合轴的整体热处理方法。此外，还研究了钢-铝化合物连接区域的裂纹扩展行为。

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.
