摘要：
The present invention relates to a hard cemented carbonitride alloy for cutting tools, which comprises 97 to 75% by weight of a hard phase and 3 to 25% by weight of a binder metal, the hard phase consisting of metallic components of titanium as a main component, 5 to 40% by weight of one or more of tungsten and molybdenum and 3 to 40% by weight of tantalum and non-metallic components of carbon and nitrogen, the proportion of nitrogen being 5 to 40% by weight of the non-metallic components and the binder metal being at least one element selected from the group consisting of iron, cobalt and nickel.
