Abstract
A high strength bulk nano-crystalline Al–1Fe–(0-1)Zr alloys were processed by mechanical alloying and spark plasma sintering. The high yield strength of ~850 MPa was achieved in an Al–1Fe–0.5Zr alloy with 19% strain in compression. The high strength was attributed to the nanosized Al–Fe grains and the dispersion of fine Al6Fe particles. High temperature compressive yield strength of 455 MPa and elongation of 16.7% was achieved at 250 ◦C.
