Abstract

This paper discusses the effects residual porosity may have on some properties of nanocrystalline materials. The two examples considered here are Young's modulus and saturation magnetization. It will be shown that the large variations observed for these properties may be explained, at least in part, on the basis of the residual porosity in thematerials which may vary considerably depending on the production techniques used to synthesize nanostructured materials.
