dcterms:description
The present trend in the automotive industry is towards lowering the weight of components whilst increasing travel safety and decreasing manufacturing costs. To this end, low-alloyed steels have been developed with high strength and ductility, and low cost owing to their low content of alloying elements. Experiments were carried out to test the design concept of thermomechanical treatments on low-alloyed high-strength steels. The aim of the experiments was to achieve high strength whilst maintaining relatively high ductility. To this end, thermomechanical processing was combined with Q&P (Quenching and Partitioning). By modelling the treatment on the FORTECH thermomechanical simulator, a microstructure was obtained formed of a martensite matrix and finely diffused retained austenite between martensitic laths. After thermomechanical treatment, the microstructure of the steel was analysed using light and confocal microscopy. The mechanical properties were validated with a tensile test.
