Abstract
Nanoscale aluminum alloy powder is synthesized by mechanical alloying/milling techniques without significant oxidation, nitridation, or contamination with foreign materials. These powders are consolidated into a very dense billet form without a high temperature sintering step. The desired microstructure and properties were obtained by post hot isostatic pressing, extrusion, and/or forging of the nanoscale material billet made from the powders.
