We report the synthesis of nanocrystalline powders of Cu, Ni, Al, NiAl, MOSi{sub 2}, and the nanocomposite Cu/TiB{sub 2}. Of these powders, Cu, MoSi{sub 2}, and Cu/TiB{sub 2} have been consolidated to densified nanocrystalline compacts by hot pressing and/or hot isostatic pressing. We will describe the use of the chemical-reduction approach, which is well-known, to provide a variety of nanostructured materials, to afford some controlled variation of crystallite sizes, and to produce strengths and hardnesses in excess of conventional coarse-grained or nanocrystalline materials prepared by other methods.
