| Abstract Scope |
After many years of intensive research, TiAl-based alloys finally became the first light-weight intermetallic materials that were successfully transferred into industrial high-temperature applications, e.g., as energy-saving turbine blades in the low-pressure range of jet engines. Properties such as the high-temperature creep strength and corrosion resistance still might be improved and the development of the next generation of TiAl-based alloys is going on. Materials design today is no longer a classical trial and error approach. Time and costs of industrial alloy developments can be significantly reduced by making use of predictions obtained by the CALPHAD method applied on thermodynamic databases such as TCTI2. The goal of the EU-project ADVANCE is to improve and update this database by generating new experimental data on phase equilibria and phase transformations in a series of ternary systems Ti-Al-X (X = Nb, Mo, W, Si, Zr, O, B, C) and two quaternary systems, Ti-Al-Nb-Mo and Ti-Al-Nb-W. |
