- Abstract: In this work a re-investigation of the solubility limits of the (Nb), Nb3 Al, Nb2 Al and the Nb-rich side of the NbAl3 phases on the Nb-Al system is presented. Alloys in the binary fields ((Nb)+Nb3 Al, Nb3 Al+Nb2 Al and Nb2 Al+NbAl3 ) were arc-melted, and then equilibrated at 1000, 1200 and 1400 °C. The phases were confirmed via X-ray powder diffractometry, and their compositions were determined via EPMA measurements. The results showed agreement with the literature concerning the solubility limits of (Nb), Nb3 Al and NbAl3 phases, while important differences in the values were found for the Nb2 Al phase. In addition, the lattice parameters of the Nb2 Al phase were determined via Rietveld refinement. This new set of more accurate experimental information indicates that a thermodynamic reassessment is necessary to precisely describe this system.
