Abstract

Verfahren zur pulvermetallurgischen Herstellung von Werkstücken, insbesondere Werkzeugen, mit in einer Matrix homogen verteilten hochschmelzenden Karbiden und/oder Karbonitriden, wobei in einer Schmelze ein Gehalt der Elemente der IV. und V. Gruppe bzw. Neben­ gruppe des periodischen Systems von mindestens 3 Gew.-%, eine niedrige Kohlenstoff-und Stickstoffkonzentration eingestellt und primäre Ausscheidungen verhindert werden und ein gewünschter Kohlenstoff-und/oder Stickstoffgehalt bei einer Verdüsung der Schmelze zu Pulver und/oder einer Diffusionsglühung des Pulvers mit einem Kohlenstoff oder Kohlenstoffverbindungen und/oder Stickstoff oder Stickstoffverbindungen aufweisenden Medium erfolgt und mindestens 10 Vol.-% Karbid und/oder Karbinitridanteil auf­ weisende Pulver gegebenenfalls nach Zumischen eines weiteren Pulvers in an sich bekannter Weise zu einem PM-Teil verarbeitet wird. Nach diesem Verfahren hergestellte Werkstücke, insbesondere Werkzeuge, weisen einen Gehalt der Elemente Vanadin und Niob und/­ oder Titan und/oder Zirkon und/oder Hafnium und/oder Tantal mit einem Karbid- und/oder Karbonitridanteil von mindestens 10 Vol.-% bei einer maximalen Karbid-und/oder Karbonitrid-Korngröße von 5µm auf. Process for the powder metallurgical production of workpieces, in particular tools with homogeneously distributed in a matrix high-melting carbides and / or carbonitrides, being in one Melt a content of the elements of the IV. And V. group or minor group of the periodic system of at least 3% by weight, one low carbon and nitrogen levels set and primary excretions are prevented and a desired Carbon and / or nitrogen content when spraying the Melt to powder and / or a diffusion anneal of the powder with a carbon or carbon compounds and / or Medium or nitrogen compounds and at least 10% by volume of carbide and / or carbinitride content pointing powder, optionally after admixing another Powder processed into a PM part in a manner known per se becomes. Workpieces produced by this method, in particular Tools, have a content of the elements vanadium and niobium and / or titanium and / or zircon and / or hafnium and / or tantalum with a carbide and / or carbonitride content of at least 10 vol .-% at a maximum carbide and / or Carbonitride grain size of 5 µm.
