Abstract

L'invention concerne un procédé de production d'un acier austénitique présentant une résistance mécanique et une aptitude au formage élevées. L'acier de l'invention présente, en pourcentage en poids, la composition chimique suivante: C 0,2-1,5; Mn 10-25; éventuellement Ni<2; 0,05-2,00; A1 0,01-2,0; N<0,1; P+Sn+Sb+As<0,2; S+Se+Te<0,5; et éventuellement Nb+Co<1 et/ou Re+W<1, l'équilibre étant apporté par Fe, en dehors des impuretés inévitables. L'acier est soumis à un traitement spécifique de recuit par recristallisation. L'invention concerne en outre le produit d'acier austénitique obtenu par ce procédé, et son utilisation dans l'industrie automobile. La figure 2 montre la microstructure d'un acier TWIP de l'invention, telle qu'elle apparaît après déformation, et dans laquelle la présence de geminés est observée.
