摘 要：<正> The microstructures of rapidly solidified （RS） Al-Fe-Ce-Ti and Al-Fe-V-Si alloys obtained bymeans of rotating blade quenching were studied with optical microscopy,transmission electronmicroscopy （TEM）.The featureless zone observed in the two alloys reveals that the new techniqueoffers a higher solidification rate than the inert-gas-atomized method.Under TEM observation thefeatureless zone presents virtually a micropartition or partitionless feature,and the solute contents init are almost the same as the chemical composition of alloys.
