Abstract

A BN based hard material contg. at least one Group 3 element (B and/or Al) as an alloying additive contains in atomic % 42-61 B, 39-50 N2, 0.04-30 Gp3 element, 0.01-2 impurities. The material is made from a mixt. of a B and N source in stoichiometric proportions and 1-50% wt. of gp. 3 element of boride. The mixt. is hot pressed at 50-95 K bar and 1500-3000 degrees C. Used for cutting tools e.g. milling cutters, drill lints, saws, for (semi) finishing cast iron and quenched steel. The prod. improved hardness and wear resistance, inert and contains no components which hydrolyse in air.
