Abstract

See full text

The invention concerns the field of hardmetal materials and relates to hardmetals such as those which can, for example, be used as cutting material for tools. The object of the present invention is to specify hardmetals which include a novel concept for the structural composition of the hardmetals. The object is attained with hardmetals which are at least made up of hard phases in particle form and metal binder arranged therebetween, wherein a high-entropy hard phase (HEH) is composed of at least four metals (Me) of the 4th and/or 5th and/or 6th subgroup of the PTE in the form of a solid solution of carbides, nitrides, carbonitrides, oxycarbides, and/or oxycarbonitrides of the metals, wherein the respective amounts of the metals in the HEH are essentially equal.
