• Within the Integrated Project IMPRESS, funded by the EU, a concerted action was taken to determine the thermophysical properties of a g-TiAl based alloys, suitable for casting large turbine blades for aero-engines and stationary gas turbines. The challenge was to develop a castable alloy, free of grain refiners and susceptible to heat treatment. Due to the high reactivity of this class of alloys, many difficulties were encountered to process the liquid phase in a crucible. This prevented the measurements of specific heat, viscosity and electrical conductivity in the liquid phase. However, surface tension and density could be measured using container-less techniques. For the surface tension determination, both the oscillating droplet method by the electromagnetic levitation and the pendant drop method by an advanced experimental complex that has been designed for investigations of high temperature capillarity phenomena were applied. A comparative discussion on the results obtained for the surface tension of Ti46Al46Nb8 and Ti46Al46Ta8 alloys, together with the corresponding theoretical values calculated by thermodynamic models is shown.
