Copper nanostructure and aluminum-alumina nanocomposite are studied using the stress relaxation technique to determine the activation volume involved in the micro-mechanism of the deformation. These materials exhibiting near-perfect elasto-plastic deformation show similar behavior in the steady state flow domain. Difference is observed when relaxations are carried out in the work-hardening domain where dislocations variation occur.
