摘要： A hard alloy includes a plurality of complex carbonitride hard phases that contain Ti as a main component element and at least one additional element selected from the group consisting of Zr, Hf, V, Nb, Ta, Cr, Mo, W, Al, and Si, and a metal binder phase containing an iron group element as a main component element. The plurality of complex carbonitride hard phases include a plurality of homogeneous composition hard phases where in-complex carbonitride hard phase average concentrations of Ti and the additional element have a difference of greater than or equal to -5 atom% and less than or equal to 5 atom% from average concentrations of Ti and the additional element in all the complex carbonitride hard phases. On any cross section specified in the hard alloy, a cross-sectional area of the homogeneous composition hard phases accounts for greater than or equal to 80% of a cross-sectional area of the complex carbonitride hard phases, and the homogeneous composition hard phases account for greater than or equal to 80% of the complex carbonitride hard phases in number.
