摘要：

Spark plasma sintering (SPS) was conducted on nanocrystalline ZrO2(Y2O3)-20 mol% Al2O3 powder at a heat rate of 600 degrees C/min with a short holding time. Full density was obtained at sintering temperatures > 1300 degrees C. Considerable grain growth occurred relative to the initial powder particles, but smaller grain size and higher density can be obtained as compared to hot-pressing. High flexural strength and fracture toughness were also achieved for the SPS-resulted composite. (C) 2000 Elsevier Science B.V. All rights reserved.
