- 論文の詳細を見る
Aluminum boron carbide (Al_8B_4C_7) was synthesized by heating a mixed powder consisting of Al:B_4C:C=8:1:6 (molar ratio) at 1600℃ for 1h. The synthesized Al_8B_4C_7 powder was ball milled for 24h with alumina balls to prepare an Al_8B_4C_7 powder with under 40μm diameter. The fine Al_8B_4C_7 powder was then put into a carbon die, pressed, and sintered using PECS at 1650℃ for 10min under an applied pressure of 60MPa, resulting in an Al_8B_4C_7 body with a relative density of 99.6%. The bending strength, Vickers hardness, and fracture toughness of the dense Al_8B_4C_7 body were 500MPa, 15.2GPa and 2.3MPa・m^<1/2>, respectively. The bending strength of the dense Al_8B_4C_7 body increased during heating to 510MPa at 1000℃, but decreased to 440MPa at 1200℃.
