Abstract
A niobium-based alloy with 20% V-15% Al (at.%) was synthesized by mechanical alloying of elemental powders. During milling, the splitting of Nb X-ray peaks into two components was observed. Each component was found to correspond to a mobium solid solution (Nb-1 and Nb-II) with a different lattice parameter. The intensities of Nb-1 peaks on X-ray diffraction patterns decreased with the milling time and disappeared completely after 180 h of milling while the intensities of Nb-II peaks gradually increased, The powders were hot pressed and micro structural and phase analyses of the consolidated material were carried out. The microstructure consisted of Nb solid solution, Nb3Al-base intermetallic with the A15 crystal structure and dispersoid Al2O3. Also an unexpected, detrimental, Nb2Al-base sigma phase was found. The volume fraction of the sigma phase depended on the temperature of consolidation.
