摘要
The microstructures of rapidly solidified (RS) Al-Fe-Ce-Ti and Al-Fe-V-Si alloys obtained by means of rotating blade quenching were studied with optical microscopy,transmission electron microscopy (TEM).The featureless zone observed in the two alloys reveals that the new technique offers a higher solidification rate than the inert-gas-atomized method.Under TEM observation the featureless zone presents virtually a micropartition or partitionless feature,and the solute contents in it are almost the same as the chemical composition of alloys.
