Metallic multilayer thin films have attracted substantial attention as some of these multilayers have high mechanical strength, close to the theoretical values. There are abundant studies on Cu based metallic multilayers. In this study, we present nanostructured Ag/Fe multilayers with various individual layer thicknesses h prepared by DC magnetron sputtering. The evolution of microstructures were characterized by x-ray diffraction and transmission electron microscopy. Size dependent strengthening behavior is observed in Ag/Fe multilayers. Comparison to our previous study on mechanical behavior of Ag/Ni multilayer system suggests that the difference in mechanical strength between the two systems arises from Koehler stress and different types of interfaces that were introduced into the systems.
