Abstract

ALLIAGES DURS CONTENANT DU MOLYBDENE ET DU TUNGSTENE. CES ALLIAGES DURS COMPRENNENT UNE PHASE DURE, SE COMPOSANT D'AU MOINS UN COMPOSE AYANT UNE STRUCTURE CRISTALLINE DU TYPE HEXAGONAL SIMPLE MC (M: METAL; C: CARBONE) CHOISIE DANS LE GROUPE SE COMPOSANT DE CARBURES MIXTES, DE CARBONITRURES ET DE CARBOXYNITRURES DE MOLYBDENE ET DE TUNGSTENE COMME COMPOSANT PREDOMINANT, ET UNE PHASE DE LIAISON SE COMPOSANT D'AU MOINS UN ELEMENT CHOISI DANS LE GROUPE SE COMPOSANT DE FER, DE COBALT, DE NICKEL ET DE CHROME, OU UNE PHASE DURE SE COMPOSANT D'UN COMPOSE DE TYPE MC, AYANT UNE STRUCTURE CRISTALLINE DE TYPE HEXAGONAL, EST DISPERSEE UNIFORMEMENT. LA PRESENTE INVENTION EST PARTICULIEREMENT UTILE POUR FOURNIR DES ALLIAGES DURS RENFERMANT DU MOLYBDENE ET DU TYNGSTENE, PARTICULIEREMENT ADAPTES A LA FABRICATION D'OUTILS DE COUPE.HARD ALLOYS CONTAINING MOLYBDENE AND TUNGSTENE. THESE HARD ALLOYS INCLUDE A HARD PHASE, CONSISTING OF AT LEAST ONE COMPOUND HAVING A SINGLE HEXAGONAL MC CRYSTALLINE STRUCTURE (M: METAL; C: CARBON) CHOSEN FROM THE GROUP CONSISTING OF MIXED CARBIDES, CARBONITRIDES AND CARBOXYNITRIDES MOLYBDENE AND TUNGSTENE AS THE PREDOMINANT COMPONENT, AND A BINDING PHASE CONSISTING OF AT LEAST ONE ELEMENT SELECTED FROM THE GROUP CONSISTING OF IRON, COBALT, NICKEL AND CHROME, OR A HARD PHASE CONSISTING OF A COMPOUND OF TYPE MC, HAVING A HEXAGONAL-TYPE CRYSTALLINE STRUCTURE, IS UNIFORMLY DISPERSE. THE PRESENT INVENTION IS PARTICULARLY USEFUL FOR PROVIDING HARD ALLOYS CONTAINING MOLYBDENE AND TYNGSTENE, PARTICULARLY SUITABLE FOR THE MANUFACTURE OF CUTTING TOOLS.
