Abstract

The phase equilibria and thermodynamic properties in the ZrO2 – DyO1.5 system have been studied using the experimental methods of X-ray diffraction, scanning electron microscopy, energy dispersive X-ray spectroscopy, differential thermal analysis and high temperature drop calorimetry. The tetragonal + fluorite and fluorite + C-Dy2O3 phase equilibria between 1400 °C and 1700 °C have been determined, together with the enthalpy increments of the materials with 30 mol.% and 50 mol.% DyO1.5 in the temperature range 200 – 1400 °C. Furthermore, the martensitic transformation temperatures (As, Ms) have been measured for the samples with 1 and 2 mol.% DyO1.5. Finally, thermodynamic assessment has been carried out using the experimental results obtained and literature data.

Keywords: ZrO2 – DyO1.5; Phase equilibria; Thermodynamics; CALPHAD
