<p>The production of moulded bodies from hard-metal powders by pressing and simultaneous or subsequent heat treatment is known. The mixture of hard material powders and aluminium powders for producing dry-pressed moulded bodies is an example thereof. As a result of the risk of demixing and the loss of homogeneity, the upper limit, for example according to prior art, for the proportion of hard material particles added to the aluminium powder is approximately 20 vol. %. The aim of the invention is to increase the proportion of hard material particles it the mixture. To this end, the inventive method for producing metal ceramic composite materials is characterised by dry-pressing powders with base compositions of between 25 and 79 vol. % of at least one metallic phase, preferably aluminium and the alloys thereof, and between 75 and 21 vol. % of at least one non-metallic inorganic constitnent, as ceramic materials, preferably silicon carbides, aluminium oxides, titanium oxides, carbon and silicates.</p> |
