An Al{sub 65}Cu{sub 20}Fe{sub 15} alloy with the composition of Al-65at%, Cu-20at% and Fe-15at% was prepared from 99.5% pure starting materials. Alloy powders were then produced with a rapidly solidified (RS) device developed by Chen et al. The powders obtained have an average particle size of about 15{mu}m and their cooling rates are estimated to be 10{sup 5}--10{sup 7} K/S. The powders were uniformly sprinkled on to microgrids for observation by transmission electron microscope (H-800 transmission electron microscope equipped with an EDAX SW9100 composition analysis system).
