Prediction of springback during indirect hot press forming through tensile test with simultaneous cooling

Abstract: Due to the demand for reduced weight, improved safety, and crashworthiness in vehicles, the need to manufacture automobile structural components from ultrahigh-strength steels is apparent. Indirect hot press forming process is a process developed from hot press forming because of steel's high resistance to trimming after hot press forming. From the researches about indirect hot press forming, considerable springback in the indirect hot press forming is accrued after preforming. After this trimming, the materia… Show more

“…Nowadays, ultra-high-strength steel (UHSS) has occupied a certain place in the automotive industry. Combined with the hot stamping process, this kind of material allows manufacturing parts with ultra-high strength, minimum springback, and reduced sheet thickness [7,8]. Because the stress level and the hardening of the UHSS decrease at higher temperatures, hot stamping allows UHSS forming of complex parts for which the production with conventional methods is either impossible or extremely difficult.…”

“…It can be divided into direct hot stamping and indirect hot stamping. The indirect hot stamping is mainly used to form sheet with complex shapes and the sheet needed to be pre-formed before heating and quenching [14][15][16]. Seo et al investigated the formability of direct and indirect hot stamping processes under different blank holding forces of ultra-high strength steel [17].…”

“…Gantner et al 18 theoretically investigated the technique of free-bending process, which is highly applied in the manufacture of car components due to fast bending speed and free definable bending geometry and verified by experiments. Huang et al 19 estimated springback of indirect hot press forming for manufacturing automobile structural components of ultrahigh-strength steels, reducing weight and improving crashworthiness, under varied cooling rate.…”
