This paper reports the effect of coolingrate on the extension of Mn solid solubility in Al and on the relative amount of MnAl (MnAl{sub 6} and MnAl{sub 4}) secondary phases during gas atomization and spray deposition critically examined. An alloy of composition Al-6.5Mn-2.3Li-0.65Zr (wt pct) currently being investigated for applications requiring high strength and low density at high temperatures was selected for this study. The material was exposed to various solidification histories by altering gas pressure and powder size during solidification.
