摘要：

This article reports the processing of fully dense Y-stabilied tetragonal zirconia polycrystal (Y-TZP)-based 30 vol.% TiB2 composites via hot pressing route using both the commercial co-precipitated and the yttria coated ZrO2 powders with nominal dopant content of 3 mol% yttria. The indentation toughness of the sintered composites is found to be strongly sensitive to the use of ZrO2 starting powders. Both the residual stress and the yttria distribution in the ZrO2 matrix are found to have a significant influence on the achievable toughness. (C) 2003 Elsevier B.V. All rights reserved.
