Powder metallurgy on its way to nanocrystalline structures
by B. Gunther, H.-D. Kunze, B. Scholz
International Journal of Materials and Product Technology (IJMPT), Vol. 8, No. 2/3/4, 1993

Abstract: Metallic and ceramic dense nanocrystalline (nc-)materials with average grain sizes of about 5 to 100 nm may be produced by means of powder technology at relatively low temperatures. This is achieved by using nano-dispersed, i.e. highly sinter-active starting powders. It is the extremely high grain-/phase-boundary area that determines the unusual properties of the resultant PM-components. The various suitable PM-methods for the production of pure as well as composite nc-materials are shortly reviewed including the sol-gel-process, mechanical alloying and the inert gas evaporation method. Some of the fascinating potentials of PM-fabricated nc-materials due to their peculiar magnetic, electronic and mechanical behaviour are elucidated.
