Abstract
The influence of cold isostatic pressing to 2.0 GPa on the phase transformations in powders of ZrO2-Y2O3 solid solutions and γ-Al2O3 is investigated. The cold isostatic pressing of ZrO2-Y2O3 is shown to lead to conversion of the tetragonal modification into a monoclinic phase. The extent of conversion decreases as the Y2O3 content and the particle size increase. In the case of γ-Al2O3 powders, cold isostatic pressing at 1.5 GPa leads to lowering of the temperature at which the aphase appears by 100 K in comparison to a γ-Al2O3 powder subjected to cold isostatic pressing at 0.1 GPa. A quantitative model, which accounts for the experimental results discovered, is proposed.
