Abstract

L'ACIER A COUPE RAPIDE DU TYPE TUNGSTENE, CONTENANT DU VANADIUM ET PRODUIT SELON LA METALLURGIE DES POUDRES A UNE DURETE A UNE TEMPERATURE ELEVEE SANS DEVOIR RECOURIR AUX HAUTES TENEURS CLASSIQUES EN COBALT. CECI EST OBTENU EN UTILISANT UNE QUANTITE CRITIQUE DE TUNGSTENE ETOU DE MOLYBDENE SUPERIEURE A CELLE EMPLOYEE ORDINAIREMENT EN COMBINAISON AVEC LE VANADIUM ET LE CARBONE, C'EST-A-DIRE UNE QUANTITE SUFFISANTE POUR SE COMBINER AVEC LE VANADIUM PRESENT ET AVEC UN EXCES DE CARBONE POUR PREVOIR UN RENFORCEMENT DE LA MATRICE. LA DURETE ELEVEE ET LA RESISTANCE A L'USURE A UNE TEMPERATURE ELEVEE SONT CONFEREES A L'ACIER PAR LES CARBURES DE VANADIUM, DE TUNGSTENE ETOU DE MOLYBDENE. LE NIOBIUM PEUT REMPLACER UNE PARTIE DU VANADIUM.
