TiCN-base cermet and cutting tool and method for manufacturing cut article using the same

摘要

A cermet comprises a binding phase made of a binding metal including Co and/or Ni. The binding phase is 5 to 30 mass %. The cermet further comprises a plurality of hard particles bound each other with the binding phase. The hard particles comprise core-containing structure particles having cores and shells both including TiCN. The core-containing structure particles comprise first core-containing structure particles of which shells contain the binding metal and second core-containing structure particles of which cores and shells both contain the binding metal.
