Abstract
L'invention concerne un procédé de fabrication d'un composant d'absorption d'énergie pour un véhicule. Le procédé inclut le chauffage d'un matériau d'acier GENS bainitique qui a une microstructure incluant de la ferrite et de la bainite à une température supérieure à la température Ac3 pour convertir une partie de la ferrite et de la bainite en austénite. Le procédé comprend en outre le formage pendant le refroidissement de l'ébauche en acier chauffé en un composant dans une matrice en acier à température régulée. Pendant l'étape de refroidissement, le matériau en acier est refroidi à une température inférieure à la température Ms pour former de l'austénite retenue. Une partie de l'austénite se transforme en martensite et en bainite pendant l'étape de formage et de refroidissement. Le procédé peut en outre inclure le chauffage du composant à une température supérieure à la température Ms après l'étape de formage et de refroidissement pour augmenter les caractéristiques d'absorption d'énergie. Pendant un accident, la contrainte imposée au composant convertit l'austénite retenue présente dans le composant en martensite.
