摘要：

A 30 vol % partially stabilized ZrO2 particle-MoSi2 matrix composite was synthesized by hot pressing to 96% theoretical density at 1700°C. No chemical reactions between the PSZ and MoSi2 were observed after hot pressing, indicating thermodynamic stability of these species. The composite formed an adherent and coherent glassy-appearing oxidation layer after oxidation at 1500°C. The room temperature indentation fracture toughness of the composite was 2.5 times that of pure MoSi2. These results demonstrate the feasibility of PSZ particle-MoSi2 matrix composites. © 1990 Chapman and Hall Ltd.
