A two phase (γ + α) titanium aluminide alloy Ti–48Al–2Cr–2Nb, at.-% was isothermally forged along all the three axes in succession at an initial forging temperature of 1273 K, followed by another two sets of forgings at lower temperatures of 1173 and 1123 K. The combined effects of heavy multiaxial strains (ɛ = 2·07, per set of forgings), progressively lower temperatures, and a moderate strain rate (10-3 s-1) transformed the microstructure to a fine and equiaxed shape. The microstructure developed is suitable for working at a low temperature.
