Abstract

Hard metal, titanium carbonitride, sintered shaped parts, cutting, steel, microstructure, particle size of hard material, fibre length distribution, median value The invention relates to a hard metal based on titanium carbonitride. Objects to which the invention relates are carbonitride hard metals which are bound with auxiliary metals and are used as sintered shaped parts, in particular for the cutting of steel. According to the invention, the microstructure of these hard metals has a narrow distribution of the grain size of the hard material, in which the fibre length distribution fulfils the condition 195/150 </= 2.5 and 0.2 mu m </= 150 </= 5 mu m is applicable for the median value 150 of this distribution and the content of titanium-rich alpha '-phase, based on the total volume of the hard material phase, is at least 15 parts by volume.
