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 : Mn / Al > 1,0. La microstructure de la tôle selon l'invention est constituée de ferrite, d'austénite et jusqu'à 5% de précipités Kappa en fraction surfacique.
