Results from scanning electron microscopy, high-energy and conventional X-ray diffraction as well as differential scanning calorimetry were used for the characterization of the prevailing phases and phase transformations. For the prediction of phase stabilities and phase transition temperatures, thermodynamic calculations using the CALPHAD method were conducted. In order to achieve better agreement between calculated and experimental results, a commercially available database was modified using our own results from thermo-physical measurements and annealing treatments.en2195-8556International Journal of Materials Research20071111311137AlloyingMicrostructurePhase predictionPhase transitionsTitanium aluminidesNatural Sciences and Mathematics::530: PhysicsNatural Sciences and Mathematics::540: ChemistryNatural Sciences and Mathematics::541: Physical; Theoretical::541.3: Physical ChemistryExperimental studies and thermodynamic simulation of phase transformations in high Nb containing c-TiAl based alloysJournal Article10.3139/146.101569Journal Article
