SINTERED BINARY ALUMINUM ALLOY POWDER, AND METHOD FOR PRODUCTION THEREOF

摘要

Disclosed is a binary aluminum alloy powder sintered material which comprises aluminum and iron, which has a completely crystalline microstructure comprising an aluminum matrix and an ±-Al phase and at least any one phase of an Al 6 Fe phase or an Al 13 Fe 4 phase mixed in the aluminum matrix as nanocrystalline phases, and which has an extremely high strength and a well-balanced high ductility, though being free from any rare earth element.
