摘要：
Al-2,4,6,8 and 10%Fe alloys were rapidly solidified by means of atomization-rolling which is a combined process of gas atomization using a single roller. Microstructure of the flake was finer than that of atomized powder. From the cell spacing of the flake, the cooling rate is estimated at 10**5-10**7 degree C/sec. The lattice constant decreased with Fe content and reached a constant value beyond 4% Fe content. The solubility of Fe was estimated at 1. 4% in the flake containing more than 4%. Hardness increased with Fe content. It was higher than that of gas atomized powder.
