Nanocrystalline (n-) Fe, n-TiO2 and a binary n-composite TiO2/ T2Y2O7 were prepared by the inert gas condensation method. For pure nanocrystalline Fe, indentation creep was measured over the temperature range 20°C - 200°C. The creep rate showed nearly logarithmic behavior in time, but increasing strongly with temperature. The ceramic samples were creep tested under uniaxial compression. The results of both indentation creep and uniaxial creep tests are explained by a Coble creep model with strain dependent activation enthalpy.
