Many unusual properties of ultrafine grain materials obtained by equal channel angular pressing (ECAP) are commonly attributed to non-equilibrium grain boundaries. Such grain boundaries are expected to exhibit higher values of energy, higher amplitude of strain fields, a larger free volume and a hig
The diffusion of 63 Ni radiotracer in ultrafine grain (UFG) Cu produced by equal channel angular pressing (ECAP) was studied using the serial-sectioning method. The diffusion annealings were performed in the temperature range of 424-553 K for annealing times at which volume diffusion is negligible a
