Title (EN) COMPOSITE SINTERED COMPACT
(FR) COMPACT COMPOSITE FRITTÉ
(JA) 複合焼結体
Abstract:
(EN) A composite sintered compact containing at least a cubic boron nitride and a binding material, characterized in that a plurality of cubic boron nitride particles are bound to each other, and thereby the cubic boron nitride has a continuous structure, and a plurality of binding material particles being present in the region except the binding interface, in which the above cubic boron nitride particles are bound to each other, and thereby the binding material also has a continuous structure.
(FR) Compact composite fritté contenant au moins un nitrure de bore cubique et un matériau de liaison, caractérisé en ce qu’une pluralité de particules de nitrure de bore cubique sont liées les unes aux autres, ce qui donne au nitrure de bore cubique une structure continue, et une pluralité de particules du matériau de liaison étant présente dans la zone excepté à l'interface de liaison, dans laquelle les particules de nitrure de bore cubiques sont liées les unes aux autres, ce qui donne une structure continue au matériau de liaison.
(JA)  本発明の複合焼結体は、立方晶窒化硼素と結合材とを少なくとも含む複合焼結体であって、該立方晶窒化硼素は、複数の立方晶窒化硼素粒子が互いに結合することにより連続した構造を有し、かつ該結合材は、上記立方晶窒化硼素粒子が互いに結合する結合界面を除く領域に存在する複数の結合材粒子が互いに結合することにより連続した構造を有することを特徴としている。
