Abstract

La présente invention concerne un composant structural pour un véhicule automobile formé d'une seule pièce de matériau d'acier et ayant une section transversale complexe fermée présentant une résistance accrue, par exemple une résistance supérieure à 650 MPa, et donc des performances améliorées. Le composant structural présente généralement un allongement supérieur à 5 %. Le composant structural est formé par la dilatation d'un matériau d'acier contenant du bore, par exemple par chauffage ou hydroformage d'un tube du matériau d'acier. Le matériau d'acier contenant du bore se dilate par au moins 2 % pendant le processus de formage, ce qui permet d'obtenir la section transversale complexe fermée, tout en obtenant également la résistance élevée. De plus, le composant structural peut être formé avec des zones d'épaisseur, de résistance, de dureté et d'allongement variables et/ou d'autres propriétés variables pour obtenir les performances souhaitées.
