Design of dual phase high strength steel sheets for autobody
The aim of the paper is to present the basic concepts of advanced high strength dual phase steels for automotive applications, including the design of chemical composition, microstructure and mechanical properties development during thermo-mechanical processing as well as characterization production technology and the potential applications of in-service performance. Dual-phase steel sheets have very good ability of absorption of kinetic energy on impact and higher strength properties. A good combination of strength and ductile properties of dual phase steels can reduce weight and improve safety (strength, stiffness, absorption energy) of an auto body.
Key words: dual phase, weight reduction, auto body, strength, absorption energy
