Effects of Austenitizing Temperature on Microstructure and Properties of Hot-Formed Steel

摘要：

　　Press hardening steel is the best solution for application of extremely high strength steel in automotive structures in order to reduce the weight of body-in-white.Effect of austenitizing temperature on the grain coarsening of a press hardening steel has been investigated by using dilatometer at first.The mechanical properties of press-hardened steel austenitized at temperature between 850 to 950oC by using a pilot hot stamping line have been investigated.The strength,especially the ultimate tensile strength, was improved by the grain refinement with lower austenitization temperature.
