n-situ heating/cooling neutron diffraction experiments were performed on a gamma-TiAl based alloy doped with Mo and/or C. The structural analysis was complemented by differential scanning calorimetry and electron microscopy. Description of high temperature alpha phase with new model of partially disordered alpha(2)'-Ti3Al phase instead of a fully disordered alpha-Ti is proposed. The atomic redistribution in the gamma phase is related to a wide alpha-transus signal on the DSC curves. Sections of temperature phase stability diagrams constructed from diffraction data for heating and cooling are presented.
