Abstract
L'invention concerne une tôle d'acier à haute résistance et degré de façonnabilité élevé compte tenu de son pouvoir d'élongation de sa résistance à l'impact, ainsi que son procédé de fabrication. Cette tôle d'acier à forte teneur en manganèse comprend, en poids: de 0,2 à 1,5 % de carbone (C); de 10 à 25 % de manganèse (Mn); de 0,01 à 3 % d'aluminium (Al); 0,03 % ou moins de phosphore (P); 0,03 % de soufre (S); 0,04 % d'azote (N); au moins un élément pris dans le groupe composé de: silicium (Si), à raison de 0,02 à 2,5 %; titane (Ti) à raison de 0,01 à 0,10 %; et de niobium (Nb) à raison de 0,01 à 0,10 %, le reste étant constitué par du fer et autres puretés inévitables. La tôle d'acier à forte teneur en manganèse peut être obtenue par laminage à chaud, par laminage à froid ou par plaquage et convient pour des tôles intérieures complexes ainsi que pour des éléments de structure pour coque d'automobile compte tenu de son aptitude au façonnage à la presse, de sa capacité d'étirement et de son indice élevé de durcissement à la contrainte. De plus, cette tôle à forte teneur en manganèse peut s'utiliser pour des pièces telles que des parties latérales avant d'une automobile, grâce, en autres caractéristiques, à son remarquable pouvoir d'absorption des chocs.
