摘要：
The nanocrystallic Al93.3-xFe4.3V0.7Si1.7Nd.(x = 0, 1.0, 3.0) alloy powder was fabricated by mechanical alloying, and the microstructural evolution of alloy powder during mechanical alloying and annealing treatment were studied. It was found that under the condition of vibration ball-milling for 96 h, the microstructure of Al93.3 - xFe4.3V0.7Si1.7Ndx, alloy powder still consisted of single a (Al) solid solution phase without the trace of presence of intermetalic compound; after the appropriate heat treatment, the microstructure of Al93.3-xFe4.3V0.7Ndx alloy powder consisted mainly of nanocrystalline alpha (Al) phase and alpha -Al-13 (Fe, V)(3) Si phase; the addition of rare earth Nd enhanced the grain refining and amorphous inclination of Al solid solution during mechanical alloying, and resulted in new phases formed after heat treatment.
