Abstract

L'invention porte sur un procédé de fabrication d'une tôle d'acier galvanisée ou recuite par galvanisation par immersion à chaud, ayant une microstructure trip, et ledit procédé comprenant les étapes consistant à : se procurer une tôle d'acier dont la composition comprend, en poids, 0,01 = c = 0,22%, 0,50 = mn = 2,0%, 0,2 = si = 2,0%, 0,005 = al = 2,0%, mo < 1,0%, cr = 1,0%, p < 0,02%, ti = 0,20%, v = 0,40%, ni = 1,0%, nb = 0,20%, le reste de la composition étant du fer et des impuretés inévitables résultant de la fusion, oxyder ladite tôle d'acier dans un four à flamme directe où l'atmosphère comprend de l'air et du combustible avec un rapport air sur combustible entre 0,80 et 0,95, de telle sorte qu'une couche d'oxyde de fer ayant une épaisseur de 0,05 à 0,2 µm est formée sur la surface de la tôle d'acier, et un oxyde interne de si et/ou mn et/ou al est formé, réduire ladite tôle d'acier oxydé à une vitesse de réduction de 0,001 à 0,010 µm/s, afin d'obtenir une réduction de la couche d'oxyde de fer, galvaniser par immersion à chaud ladite tôle d'acier réduite pour former une tôle d'acier revêtue de zinc, et, facultativement, soumettre ladite tôle d'acier revêtue par immersion à chaud à un traitement d'alliage pour former une tôle d'acier recuite par galvanisation.
