摘要：A titanium carbonitride-based alloy which is excellent in chipping resistance andwear resistance is disclosed. A hard phase is a carbide (TiMC), a nitride (TiMN) or acarbonitride (TiMCN) of Ti and at least one metal (M), other than Ti, selected from those

belonging to the groups IVa, Va and VIa of the periodic table. A binder phase contains Coand Ni as main components. When the structure of the titanium-based alloy is observedwith a scanning electron microscope, particles forming the hard phase in the alloy haveblack core parts (1) which are located on core portions to appear black and peripheralparts (2) which are located around the black core parts to appear gray. Assuming that Aand B represent particles having the black core parts (1) occupying areas of at least 30 %of the overall particles A and those having the black core parts (1) occupying areas of notmore than 30 % of the overall particles B respectively, the area ratio of the particles A tothe particles B satisfies a condition of 0.3 ≦ A/(A + B) ≦ 0.8.
