Solidification behaviour of Ti-47Al intermetallics with different carbon contents ranged from 0.9 to 1.5 (at. %) was studied. The alloys were prepared by quenching during directional solidification (QDS) technique. Directional solidification was performed in dense cylindrical Y2O3 moulds in a modified Bridgman-type apparatus at two constant growth rates and two constant temperature gradients in solid-liquid interface. The prepared alloys were studied by optical microscopy (OM), backscattered scanning electron microscopy (BSE), energy-dispersive spectrometry (EDS) and X-ray diffraction (XRD).
