Abstract

L'invention concerne une tôle d'acier laminée dont la résistance mécanique est supérieure ou égale à 600 mpa et l'allongement à rupture est supérieur ou égale à 20% ainsi que son procédé de fabrication. La composition chimique de la tôle de l'invention comprend : 0,10 = c = 0,30 %, 6,0 = mn = 15,0 %, 6,0 = al = 15,0 %, et à titre optionnel, un ou plusieurs éléments choisis parmi: si = 2,0%, ti = 0,2%, v = 0,6% et nb = 0,3% le reste de la composition étant composé de fer et d'impuretés inévitables résultant de l'élaboration. Le rapport du poids du manganèse sur celui d'aluminium est tel que :
