A titanium composite alloy (Ti –Al –Si – Zr) manufacturing process using eutectic solidification was studied by simultaneous thermal analysis up to 1480 °C. Phase transformations predicted by sections of the phase stability diagram (ThermoCalc optimisation) have been observed. The structure of the alloy was also studied by scanning electron microscopy (SEM), light optical microscopy (LOM) and X-ray microanalysis. Several patterns, unexplained on the basis of the stable phase diagrams of the system, are revealed to be associated with metastable phase transformations. The results can be used for a determination of composite applications and the optimisation of its casting technology.
