COMPOSITE SINTERED COMPACT AND SURFACE-COVERED BORON NITRIDE SINTERED COMPACT TOOL
PROBLEM TO BE SOLVED: To provide a composite sintered compact in which working precision can be increased even in working for a hardened steel or the like.SOLUTION: The composite sintered compact includes: cubic boron nitride particles and binder particles. The cubic boron nitride particles are included by 40 to 80 vol% in the composite sintered compact. The binder particles include TiCN particles. The composite sintered compact, in X-ray diffraction spectrum measured using a Cu-Kα ray as a ray source, has the first peak belonging to the (200) face of the TiCN particles in the range where Bragg angle 2θ lies in the range of 41.7 to 42.6°. Provided that the longitudinal axis y of the X-ray diffraction spectrum is defined as diffraction intensity and the maximum value of the peak height in the first peak is defined as I, in the Bragg angles 2θ respectively in two or more intersections at which straight line y=I/2 and the first peak are crossed, a difference between the maximum value and the minimum is 0.4° or lower.
【課題】焼入鋼の加工等においても加工精度を高めることができる複合焼結体を提供すること。【解決手段】複合焼結体は、立方晶窒化硼素粒子と結合材粒子とを含む。立方晶窒化硼素粒子は、複合焼結体に４０体積％以上８０体積％以下含まれている。結合材粒子は、ＴｉＣＮ粒子を含む。複合焼結体は、Ｃｕ−Ｋα線を線源として用いて測定されたＸ線回折スペクトルにおいて、ブラッグ角度２θが４１．７?以上４２．６?以下である範囲に、ＴｉＣＮ粒子の（２００）面に帰属される第１ピークを有する。Ｘ線回折スペクトルの縦軸ｙを回折強度とし、第１ピークにおけるピーク高さの最大値をＩmaxとした場合に、直線ｙ＝Ｉmax／２と第１ピークとが交差する２以上の交点それぞれにおけるブラッグ角度２θのうち、最大値と最小値との差が０．４?以下である。【選択図】なし
