Study on the Bending Formability and Strengthening–Toughening Mechanisms of Nb-Containing Ultra-High-Strength Steel for Automotive Welded Tubes

As the automotive industry accelerates its transformation toward lightweighting and high-performance design, the demand for ultra-high-strength welded tube steels in body and chassis structural components has become increasingly urgent. However, these materials face severe challenges in cold bending formability, damage...
