Experimental evidence is provided for the occurrence of the compensation effect, i.e., a linear relationship between the activation enthalpy and the logarithm of the pre-exponential factor, for grain boundary internal friction. The results of internal friction measurements in bicrystals of high puri
The blocking effect on grain boundary sliding of second phase particles is formulated by the inclusion method. From the energy consideration, internal stresses produced by the blocking particles which oppose the boundary sliding are derived. The usual grain boundary relaxation is modified and reduct
