摘要

Superfine powders with compositions 8 mol%CeO₂-0.25 mol%Y₂O₃-ZrO₂(8Ce-0.25Y-TZP), 8Ce-0.50Y-TZP and 8Ce-0.75Y-TZP were prepared by the coprecipitation method and sintered at 1500°C for 2, 3 and 6 hours respectively. 8Ce-0.25Y-TZP having martensitic transformation temperatures (M_s) above room temperature does not exhibit shape memory effect (SME) at ambient temperature. 8Ce-0.50Y-TZP shows the best SME, and the largest recoverable strain of 1.18% in the specimens sintered at 1500°C for 6 hours is attained. The M_s of the materials is closely related to its strength, and other factors such as grain size and density also have influence on the M_s.
