| Abstract Scope |
Fuel economy and enhanced safety have imposed challenges on vehicle lightweighting, driving application of ultra-high-strength steels in vehicle body. Thin-walled beam components, such as door anti-collision beams, are crucial load-bearing structures in automobiles, and typically feature an open hat-shaped cross-section, with the cross-section varying along the longitudinal direction. Nowadays, those ultra-high-strength beams are predominantly produced by hot press forming with boron steels of 1.5–2.0 GPa tensile strength, because of the great challenges to the cold forming due to the high strength and large springback. In this paper, a recently developed 2.0 GPa steel is cold formed successfully by using the roll-stamp technique into a car door beam, demonstrating the prospect of cold forming of ultra-high-strength steel. The roll-stamp forming technique employs discrete die blocks to gradually form beams with variable sections, and enables the cold forming of ultra-high-strength steels since the gradual forming mode can dramatically reduce forming load. |
