The department „metal physics“ develops novel titanium aluminide alloys (TiAl) for applications at elevated temperatures in aero engine turbines and automotive engines. In addition to the improvement of TiAl-alloy properties also processing by the cast and forging route is investigated. An emphasis is laid on the further development of the powder metallurgical route for TiAl and titanium alloys.
In addition the department also investigates other selected metallic/intermetallic materials for high temperature application as for example L12-hardened Ni- and Co-base superalloys. In all these investigations advanced characterisation methods are employed. Most prominent are high resolution and conventional transmission electron microscopy as well as diffraction experiments in in-situ specimen environments at the Helmholtzzentrum Geesthacht run beamlines of the German Electron Synchrotron (DESY).
