Title: Investigation of the effect of powder particle size distribution on the powder microstructure and mechanical properties of consolidated material made from a rapidly solidified Al-Fe-Ce alloy powder; Part 1: Powder microstructure

Abstract

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 characterized using transmission electron microscopy and X-ray diffractometry. The fine powder size distribution was found to be more desirable from the mechanical properties point of view due to the retention of metastable phases.
