Abstract

La présente invention concerne une fonte d'un fer blanc hypereutectique qui, dans une forme brute de coulée de la fonte, a une microstructure qui comprend une matrice ferreuse qui contient de 12 à 20 % en poids de chrome en solution dans la matrice, des carbures de chrome eutectiques dispersés dans la matrice, des carbures de chrome primaires dispersés dans la matrice, et éventuellement des carbures secondaires dispersés dans la matrice. Les carbures eutectiques constituent de 15 à 25 % en volume de la fo
