Within the framework of the Collaborative Research Centre 1153 "Tailored Forming", heat treatment strategies for tailored forming components are developed in the subproject A2. The aim is a local adaptation of the material properties. In addition to this local adaptation, the heating and cooling processes over the entire process chain are also to be considered, thereby resolving conflicts of interest between forming and heat treatment parameters. Since the bond zone of the joining partners represents the main challenge, the analysis of their development (layer thickness, microstructural composition) is of particular importance in all process steps. In order to perform the heat treatment, a tempering arrangement based on induction heating and air-water spray cooling is developed (see Fig. 1). Following the hardening of the steel functional surfaces, a simultaneous heat treatment of the steel-aluminium compounds can be developed and analyzed using different process routes (Fig. 2)
