Abstract

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