R Soldaat Axial crush is an important mechanism used in automotive front end structures to absorb impact energy. In this work, numerical simulation is used to investigate the crush response of a Microstructures and Flow Behavior of Ductibor® 500-AS Nov 03, 2020 · Ductibor ® 500-AS steel is used in hot-stamping applications within tailor-welded blanks to introduce more ductile, energy-absorbing regions within ultra-high strength structural components. This study aimed to explore the sensitivity of the microstructure and mechanical properties of Ductibor ® 500-AS to changes in cooling rate. For this purpose, the microstructures and hardening Open Access proceedings Journal of Physics:Conference Jun 08, 2019 · the desired material properties.

US6994350B2 - Crush zone and method for introducing

The present invention involves a method to produce crush zones in aluminum structures using controlled application of retrogression heat treatment. Selected areas of a tubular rail are retrogression heat treated to locally lower the tensile yield strength. As a result, during a crash event, initial deformation is localized in the crush zone enabling the crush pattern to be designed directly Where can Cemented Carbide be used? ALL ABOUT In particular for the smallest bores, drawing and exit cones must be perfectly co-axial in order to achieve an accurate final geometry. With cemented carbide, one can manufacture tools and drawing nibs for the full range of wire drawing applications such as high-carbon wire, steel cord for rubber reinforcement, bead wire, welding wire Dynamic and Quasi-Static Testing and Modeling of Hot Structures optimized for axial crush are often found in the front and rear crush structure of an automobile. The current work focuses on improving the performance of axial crush rails by applying hot stamped TWBs. The TWBs comprise two hot stamping steels:Usibor® 1500-AS which hardens during quenching to reach a tensile strength of 1300 MPa or higher, and Ductibor® 500-AS which
