      abstract     = {After almost three decades of intensive fundamental
                      research and development activities, intermetallic titanium
                      aluminides based on the ordered γ-TiAl phase have found
                      applications in automotive and aircraft engine industry. The
                      advantages of this class of innovative high-temperature
                      materials are their low density and their good strength and
                      creep properties up to 750 °C as well as their good
                      oxidation and burn resistance. Advanced TiAl alloys are
                      complex multi-phase alloys which can be processed by ingot
                      or powder metallurgy as well as precision casting methods.
                      Each process leads to specific microstructures which can be
                      altered and optimized by thermo-mechanical processing and/or
                      subsequent heat treatments. The background of these heat
                      treatments is at least twofold, i.e., concurrent increase of
                      ductility at room temperature and creep strength at elevated
                      temperature. This review gives a general survey of
                      engineering γ-TiAl based alloys, but concentrates on
                      β-solidifying γ-TiAl based alloys which show excellent
                      hot-workability and balanced mechanical properties when
                      subjected to adapted heat treatments. The content of this
                      paper comprises alloy design strategies, progress in
                      processing, evolution of microstructure, mechanical
                      properties as well as application-oriented aspects, but also
                      shows how sophisticated ex situ and in situ methods can be
                      employed to establish phase diagrams and to investigate the
                      evolution of the micro- and nanostructure during hot-working
                      and subsequent heat treatments.},
