Data-based lifetime prediction for a function-oriented induction hardening process. (T06*)

• Subject Area: Primary Shaping and Reshaping Technology, Additive Manufacturing
• Term: since 2023
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 223500200

The aim of the project is to predict the process parameters of an induction hardening process for a given fatigue strength of shafts in the sense of a function-oriented production by inverting the process signature and the local fatigue strength calculation. The method will be evaluated using a sample component together with the industrial partner. The transfer project develops process signatures for the purely thermal processing of rotationally symmetrical components and uses the calculated local strengths and three-dimensional stress tensors to calculate the fatigue strength with the weakest-link model. The parameters for these calculations are determined by experimental investigations in various initial states and rotary bending tests in the induction-hardened state.
