| Abstract Scope |
The combination of high strength and good ductility are very desirable for functional structures. Laser ridgeline quenching, as a relatively new technology to reinforce steels, gives a flexible to balance the rigidity and toughness of the tubular structures like A-pillar and sill. However, the deformation incompatibility, which is caused by partial quenching, could lead to a structural fracture under impact conditions.
In this study, we suppose to investigate the plastic deformation and fracture behavior of partial quenched hot forming steel HR1500. First, quasi-static and dynamic tensile tests are conducted on the original and laser-quenched steels. Second, tensile tests are conducted on the partial quenched steels with three different boundary directions. Finally, the scanning electron microscopy-based electron backscatter diffraction is used to characterize the micro-structure evaluation and the feature of fracture of materials. |
