Technical Paper


Ti–Al–Nb composites were produced by solid state diffusion bonding through hot pressing and rolling followed by annealing at 700 °C for 0.5, 1, 1.5 and 2 h. The morphologies of TiAl3 intermetallics were investigated by Scanning Electron Microscopy combined with Energy-dispersive X-ray spectroscopy. Titanium tri-aluminide (TiAl3) particles with blocky morphology were dispersed into Aluminum matrix. In the presence of niobium and copper, TiAl3 particles were produced in different sizes and morphologies. The presence of Nb in the composite led to the formation of irregular angular morphology, while the copper resulted in cubic morphology of the intermetallic particles. The EDS results indicated that TiAl3, (Ti, Nb)Al3 and (Ti, Nb, Cu)Al3 intermetallic compounds appeared near Ti zone, Nb Zone and in the presence of Cu, respectively.
