Clean nanocrystalline powders and articles made therefrom |
| abstract |
ABSTRACT OF THE DISCLOSURE A process for the production of a powder having a nanocrystalline structure from powders of at least two materials of the groups including metals, metallic compounds, and ceramic materials, in a composition which tends to develop an amorphous phase. The starting powders are subjected to high stresses of at least 12 G in a neutral or reducing atmosphere at about 20°C until there are no crystal-lites larger than about 10 nm. |
