Abstract

As a solution to difficulties encountered in the development of-fiber reinforced materials, the use of particulates as toughening constituents appears more near-term, and to a certain extent is economically rather appealing, because of simplicity of processes. When synthesizing with ZrO2 these tougher materials, it has been found that retention of the tetragonal structure at room temperature is critically dependent upon the dimensions of the microstructure. Peculiarly, a critical grain or inclusion size exists, below which the high temperature tetragonal phase can persist, and above which retention is not observed (1).
