Abstract

Le procédé selon l'invention se distingue par l'utilisation d'un acier contenant 2,1 à 6 % de Mn, 0 à 1,5 % de Ni, 0 à 1,0 % de Si et pas plus de 0,25 % de C, le reste étant du fer et des impuretés éventuelles, et le recuit de l'acier à une température comprise dans la plage A ? à A ? + 75 degrés C pour former au moins 1 % en volume d'austénite fixée aux joints des grains, et pas plus d'une quantité négligeable d'austénite non fixée.
