Summary

An analysis has been developed which relates the effects of inelastic behavior of Y2O3-stabilized ZrO2 (YSZ) materials. The results show these materials to be sensitive to small changes in temperature and are supported by measurements of inelastic behavior in disk and bar specimens at temperatures as low as 1010°C (1850°F). At higher thermomechanical loads, the test specimens can deform to strains >1% and for bar specimens, with sufficient strength, to remain bonded to the metallic substrate.
