Abstract

L'invention concerne un procédé de fabrication d'une tôle d'acier haute résistance ayant une résistance à la traction supérieure à 1100 mpa et une limite d'élasticité supérieure à 700 mpa, un allongement uniforme ue d'au moins 8,0 % et un allongement total d'au moins 10 %, faite d'un acier contenant en pourcentage en poids: 0,1 % = c = 0,25 %, 4,5 % = mn = 10 %, 1 % = si = 3 %, 0,03 % = al = 2,5 %, le reste étant constitué de fe et des impuretés résultant de la fusion, la composition étant telle que l'indice cmn = cx (1 + mn/3,5) = 0,6, le procédé comprenant les étapes de recuit d'une tôle laminée faite dudit acier en l'immergeant à une température de recuit ta supérieure au point de transformation ac de l'acier mais inférieure à 1000 °c, de refroidissement de la feuille recuite à une température de trempe qt comprise entre 190 °c et 80 °c à une vitesse de refroidissement suffisante pour obtenir une structure juste après refroidissement contenant de la martensite et de l'austénite résiduelle, de maintien de la tôle d'acier à une température de survieillissement pt comprise entre 350 °c et 500 °c pendant une durée de survieillissement pt supérieure à 5 s en refroidissant la tôle jusqu'à la température ambiante. L'invention concerne la tôle obtenue.
