Motivation and Objectives:
For the minimisation of the hard maching cost after the case hardening, it is necessary to predict the residual stresses and the distortion, resulting out of the heat treatment, as exact as possible. To realise the this objective, the process steps carburisation and quenching of the case hardening will be mapped with the aid of the Finite Element Method (FEM). Therefore, the diffusion of the carbon will be taken into account in the simulation of the carburisation. The resulting carbon distribution in the component will be transfered into the quenching simulation. Furthermore, homogenisation methods will be implemented to map the mechanical and thermo-physical material behaviour. | |
