SINTERED BODY, METHOD FOR PRODUCING SINTERED BODY, AND CUTTING TOOL
To improve chipping resistance of a sintered body.SOLUTION: A sintered body comprises an oxide of aluminum (Al), an oxide of zirconium (Zr), and a carbide of tungsten (W) including WC and W2C. When the amount of WC measured by micro-section X-ray diffraction at a depth of 1000 μm or more from a surface of the sintered body is V1 vol.% and the amount of W2C is V2 vol.%, 0.10≤V2/(V1+V2)≤0.90 is satisfied; and when strongest X-ray diffraction peak intensity of WC measured by micro-section X-ray diffraction in a range from a surface of the sintered body to a depth of 50 μm is I1 and strongest X-ray diffraction peak intensity of W2C is I2, I2/(I1+I2)≤0.05 is satisfied.SELECTED DRAWING: Figure 1
【課題】焼結体の耐欠損性を向上する。【解決手段】焼結体は、アルミニウム（Ａｌ）の酸化物と、ジルコニウム（Ｚｒ）の酸化物と、ＷＣ及びＷ２Ｃを含むタングステン（Ｗ）の炭化物と、を含む。前記焼結体の表面から深さ１０００μｍ以上の位置において微小部Ｘ線回析で測定したＷＣの量をＶ１体積％とし、Ｗ２Ｃの量をＶ２体積％とした場合に、０．１０≦Ｖ２／（Ｖ１＋Ｖ２）≦０．９０を満たし、焼結体の表面から深さ５０μｍまでの範囲内において微小部Ｘ線回析で測定したＷＣの最強Ｘ線回折ピーク強度をＩ１とし、Ｗ２Ｃの最強Ｘ線回折ピーク強度をＩ２とした場合に、Ｉ２／（Ｉ１＋Ｉ２）≦０．０５を満たす。【選択図】図１
