Application of Next-generation High-lambda-type High-strength Steel Sheets
次世代高λ型高強度鋼板の適用
High strength steels have been applied to the automobile body as a means to reduce weight and improve crash safety performance. In order to satisfy press formability and part performance, improvement of material properties was required. Studies of press forming and crash performance showed the lambda value, or hole expansion ratio, to be especially important for improving formability and part performance. Application to body components, that could not achieved with conventional steels, was realized by the development of the new high strength steel sheet with high elongation and high local ductility自動車ボディの軽量化と衝突安全性のため，高強度鋼板の適用拡大が進められている． しかし，プレス成形性と部品性能を満足させるためには，材料特性の向上が課題であった． 今回，新しく高伸び型および高局部延性型の高強度鋼板を開発することにより，従来採用が難しかったボディ骨格部品への適用を実現した．
