Summary

The microstructure and high temperature mechanical properties of 5 mol% Er2O3 doped ZrO2 fibers were studied at temperatures between 1300 d̀C and 1570 d̀C by tensile creep tests, and bulk crystals by constant strain rate compression tests at 1400 d̀C. The microstructure of the as-fabricated and plastically deformed crystals was characterized by scanning electron microscopy. The hardening characteristics, structure of activated slip planes, and saturation of creep strain are discussed. The mechanical properties are compared with other zirconia alloys.
