| Abstract Scope |
Most of the steel grades used for making automotive structural components are subjected to low tempering treatments (LTT) during manufacturing operations. Depending on part routing and requirements, tempering related phenomena take place during e-coating baking, stress-relief annealing, and hydrogen bake-out processes. Aiming to gain better understanding of the tempering process of martensitic steel grades used in hot stamping operations, the influence of the tempering parameters (i.e., time-temperature) on the tensile response and bendability of an industrially produced Al-Si coated 22MnB5 steel is reported in this work. To study the tempering kinetics, the steel was subjected to tempering treatments at temperatures ranging from 140 °C to 500 °C. Strength softening, plane strain bending, and impact absorption are evaluated to elucidate the effects of the tempering process on the mechanical behavior, while addressing various challenges associated with the performance of high strength martensitic steels utilized in automotive applications. |
