Abstract

The concept of a novel hybrid process which includes local heat treatment for springback reduction in deep drawing of AHSS is presented. In order to demonstrate the feasibility of this process a prototype tool for deep drawing of U-profiles was designed and optimized for integrating an inductive heating coil. Both, cold forming as well as local heat treatment, were performed within a single process step, as the radius zones of the deep-drawn U-profile were heated immediately after completing the forming stroke. To quantify the influence of the local heat treatment on the internal stresses inside the U-profile, a two-dimensional model of the hybrid forming–heating process was built using the Abaqus finite element (FE) software package. The flow curves required for this model were determined by tensile testing of dual-phase (DP) steel sheets at temperatures between 25 °C and 1000 °C. Both, the experimental and the numerical results, confirm that local heat treatment can significantly reduce the local internal stresses and the springback without decreasing the overall strength of the component.
