抄録

Si₃N₄ whisker/Al₂O₃ composites with various amounts of interfacial β-SiAlON (β′-phase, Si_6-ZAl_ZO_ZN_8-Z) were prepared while controlling the hot-pressing temperature and duration. X-ray diffraction analysis revealed that interfacial chemical reaction produced X-phase and β-SiAlON with a Z-value of approximately 4. A model of the interfacial chemical reaction was proposed to explain the experimental results. The mechanical properties of the composites hot-pressed above 1600°C were markedly different from those of the composites hot-pressed below 1600°C, because X-phase at the whisker/matrix interface was liquefied during the hot-pressing above 1600°C and vitrified X-phase seemed to increase interfacial bonding strength.
