Size effects on metals and alloys that have external dimensions on the micron scale and smaller have been questioning the scientific community for several years. We have shown that these effects can be rationalized in terms of defects structure that is both sampled or altered during the fabrication processes and hindered by internal or surface effects when plastic flow has to develop.
