The high temperature behavior of as-cast Ti–46Al, Ti–45Al–7Nb and Ti–45Al–7Ta (in at.%) alloys at 800°C was investigated in this work. The structure, hardness and bending strength of the as-cast alloys were characterized. During long-term (460h) annealing of the alloys at 800°C, the structural changes were examined, and the development of hardness was monitored. The creep behavior at 800°C was studied...
