In the present investigation a potential aerospace aluminum alloy made
from atomized powder was subjected to microstructural investigation.
Samples exhibiting varied powder size distribution, due to differences
in atomizing conditions employed in powder production, were studied.
The alloy having a target composition of Al-8 wt.%Fe-4wt.%Ce was chara
cterized using transmission electron microscopy and X-ray diffractomet
ry. The fine powder size distribution was found to be more desirable f
rom the mechanical properties point of view due to the retention of me
tastable phases.
