Abstract:Nanostructured materials with average grain or other structural domain size below 100nm, have some properties different from and often superior to, those of conventional materials that have phase or grain structures on a coarse scale. In this paper nanostructured Fe3Al intermetallic compounds were produced by hydrogen arc plasma method. The TEM experiments show that the average grain size of the particles is about 40nm. Hardness of Fe3Al nano nanostructured intermetallic compounds treated by different ways was discussed.
