Phase equilibria and ordering in the system zirconia-hafnia-yttria
Description
The phase equilibria in the system zirconia-hafnia-yttria were investigated at 13000 and 16000C by precise lattice parameter measurements and the direct phase-inspection method. Large fluorite solid solution regions were dominant at both investigated temperatures. The extent of ordering within the ternary system was studied in the samples containing 40 mol% yttria at 13000C. The δ-phase (ZrHf)/sub 3/Y/sub 4/O/sub 12/ formation was established only in those samples with less than 15 mol% hafnia
