摘要：
A bulk nanocrystalline Al-5 at.% Fe alloy was synthesized by mechanical alloying and spark plasma sintering. The alloy exhibited a very high compressive yield strength of 1 GPa with a plastic strain of 0.3. The alloy consists of coarse alpha-Al grains that form from powder boundaries and nanocrystalline regions composed of alpha-Al and Al6Fe phases. The combination of the coarse and nanoscale grains are considered to be the reason for the large plastic strain in such a high-strength material. (c) 2007 Acta Materialia Inc.
