Abstract

La présente invention concerne du super acier bainitique qui comprend de 90 % à 50 % de bainite, le reste étant de l’austénite, dans lequel le carbone excédentaire reste à l’intérieur de la ferrite bainitique à une concentration au-delà de la concentration compatible avec l’équilibre. Il y a également un cloisonnement partiel du carbone dans l’austénite résiduelle. Un tel acier bainitique comporte de très minces plaquettes de bainite (épaisseur de 100 nm ou moins). Dans cette spécification, l’expression « super acier bainitique » est utilisée pour un tel acier. En particulier, l’impact de la variation de la teneur en manganèse pour obtenir des durées courtes de transformation et, de ce fait, de faibles coûts de fabrication en l’absence de matériaux d’alliage onéreux, est discuté. Dans un mode de réalisation de l’invention, un super acier bainitique comprend, en pourcentage en poids : carbone, de 0,6 à 1,1 %, silicium, de 1,5 à 2,0 %, manganèse, de 0,5 à 1,8 %, nickel, jusqu’à 3 %, chrome, de 1,0 à 1,5 %, molybdène, de 0,2 à 0,5 %, vanadium, de 0,1 à 0,2 %, le reste étant du fer sauf pour les impuretés accessoires. En particulier, on a remarqué que d’excellentes propriétés étaient obtenues si la teneur en manganèse était d’environ 1 % en poids. Divers procédés de fabrication du super acier bainitique sont exposés, mais un procédé particulièrement utile comprend l’étape consistant à refroidir l’acier à partir d’une austénite, suffisamment rapidement pour éviter une transformation en perlite et à transformer l’acier en bainite à une température comprise dans la plage entre 190 °C et 2 500 °C. Le brevet parle de l’impact du changement de la température de transition sur la dureté et conclut que l’invention peut donner un acier très dur (> 630 HV). On remarque également qu’une perlite adaptée peut être produite pour la découpe, le forage et le profilage, avant une transformation finale en super acier bainitique.
