Influence of Gd content on the room temperature mechanical properties of Gd-doped ceria
Abstract
High-density ceramics of ceria doped with 0, 3, 5, 10, 15 and 20 mol.% Gd and with grain sizes exceeding 1.5 mu m were investigated by nanoindentation. The deduced elastic moduli are independent of Gd content and remain close to the value reported for bulk ceramics (210 +/- 5% GPa). All ceramics exhibit transient creep with displacement proportional to the 1/3 power of the time. For 0.05 <x <0.2, the derived creep magnitude parameter decreases linearly with increasing Gd content. These results strongly suggest that defect rearrangement influences the measurements.
