Abstract

L'invention concerne de la fonte ductile permettant d'élaborer des composants à propriétés de résistance et de ténacité désirées. Cette fonte ductile est de type à grains fins. Ladite fonte ductile à grains fins (FGDI) comprend, en valeurs exprimées en pourcentage en poids : entre 3,6 % et 2,8 % de C ; entre 1,3 % et 2,6 % de Si ; entre 0,065 % et 0,025 % de Mg ; entre 0,8 % et 0,1 % de Mn ; entre 0,1 % et 1,6 % de Cu ; entre 0,2 % et 2,0 % de Ni ; entre 0,03 % et 0,005 % de P ; et entre 0,003 % et 0,01 % de S. La densité en sphères de graphite de la fonte ductile à grains fins (FGDI) est comprise entre 150 et 400 sphères/mm2. L'invention concerne également un procédé de fabrication de fonte ductile pour l'élaboration de composants à propriétés de résistance et de ténacité désirées. Dans ce procédé, des matières premières sont mises en fusion par fusion par induction (21), dans les phases de traitement de fusion, la matière en fusion est sphéroïdisée (22), inoculée (23) et coulée (24). Après la phase de décochage de la matière coulée (25), les opérations secondaires de coulée sont effectuées (26). Pour la fabrication de la fonte ductile à grains fins (FGDI), les pièces sont traitées thermiquement par traitement URVA 850 (28).
