Claims (3)

OBJECT OF THE INVENTION i 1. A titanocarbonitride sintered material, in particular for tri-load loading, characterized in that it consists of a matrix of the base composition (Ti, C, N, O, M) with metal supplementary carbides and other phases of the integral base composition (Ti, 0, M), wherein the total composition of the hard alloy in the molar proportions of Ti 1 and C. bc ° dMe is a range of 0.42, 02 0.84 bc 0.059 to 0.39 0 s 0.012 to 0.21 ds 0.020 to 0.14 e = 0, M represents metals, manganese, iron, nickel and / or cobalt. 2. The titanocarbonitride sintered material according to claim 1, wherein the ratio of titanium to carbon or nitrogen from the region to the center of the solids grain is reduced. 3. A titanocarbonitride sintered material according to claim 1, characterized in that it comprises 0.5 to 10.0% by weight of additional metal carbides of subgroups 4a to 6a of the perimetric array of elements. 256947
