Title (EN) CUTTING TOOL
(FR) OUTIL DE COUPE
(JA) 切削工具
Abstract:
(EN) Provided is a cutting tool containing a sintered body which includes a first hard phase, a binder phase, and Al2O3. The first hard phase comprises WC. The binder phase contains a first metal comprising at least one selected from Co and Ni as the primary components, and further contains C and a second metal comprising at least one selected from Al and W. The Al2O3 is dispersed in the sintered body.
(FR) L'invention concerne un outil de coupe contenant un corps fritté qui comprend une première phase dure, une phase liante et de l'Al2O3. La première phase dure comprend du carbure de tungstène (WC). La phase liante contient un premier métal comprenant au moins un élément choisi parmi Co et Ni en tant que composants primaires, et contient en outre du carbone et un deuxième métal comprenant au moins un élément choisi parmi Al et W. L'Al2O3 est dispersé dans le corps fritté.
(JA) 切削工具は、第1硬質相、結合相およびAlを含む焼結体を含む。第1硬質相はWCからなる。結合相は、主成分としてCoおよびNiから選択される少なくとも1種からなる第1金属を含み、さらに、AlおよびWから選択される少なくとも1種からなる第2金属と、Cと、を含む。Alは、焼結体中に分散している。
