Abstract

L'invention fournit : une plaque d'acier épaisse de haute résistance mécanique pour structure dotée d'excellentes propriétés d'arrêt de propagation de fissures cassantes mise en œuvre sur un navire et d'épaisseur adéquate supérieure ou égale à 50nm; et un procédé de fabrication de celle-ci. Plus précisément, l'invention concerne une plaque d'acier épaisse dotée d'excellentes propriétés d'arrêt de propagation de fissures cassantes, et qui est caractéristique en ce que sa texture métallique consiste essentiellement en bainite, en qu'elle possède une texture de degré d'intégration (I) d'une face RD//(110) dans une partie centrale de l'épaisseur de plaque supérieur ou égal à 1,5, et en ce qu'elle présente une température de transition de fracture de Charpy (vTrs) dans une partie couche superficielle et dans la partie centrale de l'épaisseur de plaque inférieure ou égale à -40°C. De préférence, le degré d'intégration (I) de la face RD//(110) et la température de transition de fracture de Charpy de la partie centrale de l'épaisseur de plaque, satisfont la formule (1) suivante : vTrs(1/2t)-12×IRD//(110)[1/2t]≦-70・・・(1). vTrs(1/2t) : température de transition de fracture de la partie centrale de l'épaisseur de plaque (°C); etI RD//(110)[1/2t] : degré d'intégration RD//(110) de la partie centrale de l'épaisseur de plaque.
