Abstract

The feasibility of using mechanically alloyed powders for the production of bulk nanophase alloys has been studied. Nano-grained metallic alloys, a Fe-29Al-2Cr intermetallic and a Cu-Fe two-phase composite, have been produced by high-energy ball milling. Using a recently-developed sinter-forging procedure, we have consolidated these powders into full-density compacts. Transmission electron microscopy studies show that grain sizes in consolidated samples have been retained to below 100 nm. Factors contributing to the success of the retention of nanoscale grain sizes are discussed.
