Abstract

A nanopowder ofFe3Alwas synthesized from 3Fe and Al by high-energy ball milling. A dense nanostructuredFe3Alwas consolidated by pulsed current activated sintering method within 2 minutes from mechanically synthesized powders ofFe3Aland horizontally milled powders of 3Fe+Al. The grain size, sintering behavior, and hardness ofFe3Alsintered from horizontally milled 3Fe+Al powders and high-energy ball milledFe3Alpowder were compared.
