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 2: Mechanical properties

Abstract

In the present investigation, the mechanical properties of an elevated temperature aluminum alloy exhibiting two different size distributions was evaluated after extrusion processing at 400 C. The alloy powder with a target composition of Al-8 wt.% Fe-4 wt.% Ce was produced under different atomizing conditions. The consolidation process using extrusion was found to be more beneficial for finer powder size distribution in terms of elevated temperature mechanical properties because of the retention of a more desirable metastable phase.
