Abstract
This invention relates to a cemented carbonitride alloy in which the hard phase consists of EQU [(Group IVa metal).sub.A (Group Va metal).sub.B (Group VIa metal).sub.C ]-(C.sub.X N.sub.Y).sub.Z wherein A, B, C, X and Y are respectively mole fractions, Z is a mole ratio of the metalloid components to the metal components and there are among A, B, C, X, Y and Z the relations of EQU A + B + C = 1, X + Y = 1, EQU 4a + 5b + 6c + 4xz + 5yz .gtoreq. 8.6, EQU 0.05 .ltoreq. y .ltoreq. 0.50 and 0.85 .ltoreq. Z .ltoreq. 1.0. the hard phase is combined by at least one binder metal from the iron group and there are in the alloy structure WC phase and the hard phase having the crystal structure B1 and containing Ti in a proportion of at least 20 atomic percent to the metallic atoms.
