Research of Microstructurally Developed Toughening Mechanisms in Ceramics. Part 4. Fabrication, Fracture Toughness and Strength of Al2O3/ZrO2 Composites.

Abstract

Three Al2O3/ZrO2 composite series, containing O, 2 and 7.5 mole % Y2O3, were fabricated for fracture toughness determinations. Without Y2O3 additions, 2 m/o Y2O3 allowed full retention up to 60 v/o ZrO2. Cubic ZrO2 was produced with additions of 7.5 m/o Y2O3. Significant toughening and strengthening was achieved when tetragonal ZrO2 was present. (Author)
