Abstract

Procédé de production d'alliages durs et nouveaux produits ainsi obtenus. Ces alliages se composent d'une phase métallique et d'une phase dure ayant une structure cristalline du type B1, représentée par la formule générale : (M 1a , M2b , M3c ) (C1-x-y Ny Ox ) z où M1 est au moins un des éléments du groupe IVa, M2 est au moins un des éléments du groupe VIa, M3 est au moins un des éléments du groupe Va, C est le carbone, N est l'azote, O est l'oxygène, a, b, c, x et y sont respectivement les rapports en atome satisfaisant aux relations a + b + c = 1, 0,1 <= (a + c)/(a + b + c) <= 0,7 (c peut être 0), 0,05 <= x <= 0,5, 0 <= y <= 0,5, 0,05 <= x + y <= 0,6 et z est le rapport en atome (C + N + O)/(M1 + M 2 + M3 ) satisfaisant à la relation 0,1 <= Z <= 0,5. La présente invention est particulièrement utile pour fournir des alliages durs, utilisés notamment dans des outils de coupe.Process for the production of hard alloys and new products thus obtained. These alloys consist of a metallic phase and a hard phase having a crystal structure of the B1 type, represented by the general formula: (M 1a, M2b, M3c) (C1-xy Ny Ox) z where M1 is at least one of the elements of group IVa, M2 is at least one of the elements of group VIa, M3 is at least one of the elements of group Va, C is carbon, N is nitrogen, O is oxygen, a, b, c, x and y are respectively the atomic ratios satisfying the relations a + b + c = 1, 0.1 <= (a + c) / (a + b + c) <= 0.7 (c can be 0 ), 0.05 <= x <= 0.5, 0 <= y <= 0.5, 0.05 <= x + y <= 0.6 and z is the atomic ratio (C + N + O ) / (M1 + M 2 + M3) satisfying the relation 0.1 <= Z <= 0.5. The present invention is particularly useful for providing hard alloys, used in particular in cutting tools.
