Abstract (en)

To improve the heat resistant properties of sintered hard metals, in particular with a view to achieving greater cutting powers during use as the cutting tool, it is proposed to alloy aluminium-containing complex nitrides and/or aluminium-containing complex carbides, in particular from the family comprising the H, chi or kappa phases, with the binder metal to which at least one hard material phase has been added.

Abstract (de)

Zur Verbesserung der Warmfestigkeitseigenschaften von Sinterhartmetallen, insbesondere im Hinblick auf die Erzielung höherer Schnittleistungen bei Verwendung als Schneidwerkzeug, wird der Vorschlag unterbreitet, dem mit zumindest einer Hartstoffphase versetzten Bindermetall aluminiumhaltige Komplexnitride und/oder aluminiumhaltige Komplexcarbide, insbesondere aus der Familie der H-, Chi- oder Kappa-Phasen, zuzulegieren.
