摘要：
The ultrafine-grained beta-Sialon ceramics were fabricated by spark plasma sintering at different temperatures with inorganic Al2O3-Y2O3 and Ti-22Al-25Nb intermetallic powder as composite additives. The research showed that beta-Sialon ceramics achieve two-stage sintering densification. Al2O3-Y2O3 inorganic additives promoted the synthesis and densification of beta-Sialon ceramics at 1125-1215?. Ti-22Al-25Nb intermetallic powder diffused Ti and Nb elements at 1240-1425?, thereby improving the fracture toughness of beta-Sialon ceramics. The maximum fracture toughness (similar to 9.69 MPa m(1/2)) under 19.6 N was obtained for beta-Sialon ceramics sintered at 1600?.
