title = "Sinter-forging of nanocrystalline TiO2",
abstract = "Sinter-forging experiments were performed on cylindrical samples of n-TiO2 at various stresses and temperatures and with varying initial densities. The results are described on the basis of a constitutive law similar to creep deformation of dense bodies. The activation enthalpy measured is consisted with a grain boundary diffusion limited process, whereas the stress exponent found excludes simple diffusional creep. Furthermore, a threshold stress was found to exist. The results are discussed in terms of existing models and it is shown that the threshold stress can be explained in terms of the creation of additional surface area due to grain boundary sliding.",
