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 similar to 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 degrees C. (C) 2012 Elsevier B.V. All rights reserved,
