Creep and diffusion Transitory creep and equilibrium kinetics of population of point defects in Co 1-x O

Abstract
Transitory creep, obtained after a sudden change in oxygen partial pressure, with stress and temperature remaining constant, has been studied for Co1-xO between 1000 and 1400°C. It is shown that the transitory creep is related to the chemical diffusion of point defects. Information on the mechanisms for the creation and migration of minority point defects of the oxygen sublattice has been deduced.
