Three A1203ZrO2 composites series, containing 0, 2, and 7.5 mole Y203, respectively, were fabricated. For the A1203ZrO22MoY203 series, tetragonal ZrO2 was retained from one end-member to the other. Significant increases in fracture toughness and strength were observed for materials in this system. Strengths decreased with increasing temperature. These results are consistent with previous theoretical predictions. Author
