Influence of hot-stamping conditions on residual stress profiles in a coated press-hardened steel
Press-hardened steels, such as USIBORŠ grades, have been increasingly developed in the last 10 years for their lightweight potential in automotive industry. They have an AluSiŽ150 coating to prevent from corrosion. During hot stamping, after austenitizing, a martensitic transformation occurs while the part is formed between dies. The simulation of such a process requires an extreme precision upon a wide range of physical topics, namely mechanics, thermic and metallurgy.A micromechanical modeling has been developed by the proposers and implemented in a fnite element simulation. The aim of this proposal is to validate the mechanical approach of the model by comparison of experimental and numerical residual stress profiles. The presence of the coating and the complex geometry of hot-stamped parts is a real difficulty for lab X-ray diffraction ; using neutron diffraction is mandatory to overcome it. Residual stress profiles will be determined on diffrent hot-stamped parts with increasing geometry complexity and forming strain path.
