The structure of the samples was studied using TEM and XRD techniques and the fracture surfaces were investigated employing SEM. The results of this study indicated that annealing at 250°C modified grain size distribution slightly but resulted in a significant increase in the initial strain hardening rate. While the average grain size in the 400°C sample was increased to 59nm, its yield strength was comparable to the as-deposited alloy with a 9nm grain size. The plastic tensile elongation of all annealed samples was lowered significantly to less than 1% from approximately 6% in the as-deposited state. These results are discussed in terms of the inhomogeneity of plastic deformation and the evolution of internal stresses in nanocrystalline materials.
