Creep of CoO single crystals.The crystals were creep tested in compression over ranges of temperature, stress, and oxygen pressure. The creep curves were S-shaped, and only the inflection creep rate was analyzed. A formula is presented for the inflection creep rate in the range from 1000 to 1200 C, 850 to 1700 psi, and 0.001 to 1 atm oxygen. Slip was found to occur on two orthogonal slip systems. The presence of subboundaries was observed by optical and transmission electron microscopy. It is suggested that the creep rate is controlled by oxygen diffusion.
