Abstract
Alloy powder of the Ti–47Al–2Nb–2Cr composition (at.%) with the structure of TiAl (60 wt.%) and Ti3Al (40 wt.%) is prepared by the calcium-hydride method. The mode of the calcium-hydride synthesis is optimized for the Ti–50Al (at.%) model alloy. It is established that the reduction temperature should be no lower than 1100 °C, while the excess of the CaH2 reducing agent should be no lower than 15 wt.%. The main physicochemical and manufacturing properties of the synthesized Ti–47Al–2Nb–2Cr powder alloy, which provide the formation of dense compacts during its subsequent consolidation processes, are determined using modern analytical methods.
