Ein induktives Messverfahren zur Bestimmung der elektrischen Leitfähigkeit an unterkühlten Metallschmelzen
An apparatus for non-contact maesurements of the electrical resistivity of undercooled metallic melts was developed. It combines containerless positioning by electromagnetic levitation with an inductive technique of conductivity determination. The specimen is inserted in the center of a measurement …

Untersuchungen der Strukturstabilität von Ni-(Fe)-Basislegierungen für Rotorwellen in Dampfturbinen mit Arbeitstemperaturen über 700 C
There is a continuous trend to improve the efficiency of modern power plants with steam turbine require operating steam temperature from 700 to 720°C. For substantial parts like turbine rotors and discs this means increased requirements on the high temperature resistance, which can not longer be …

Plastic behaviour of quasicrystals and related intermetallic phases
In the present work, the plasticity of quasicrystals, metallic glasses and structurally complex alloy phases was investigated. The concepts of plasticity for simple crystalline materials cannot be applied to these materials without substational modification. Plastic deformation experiments and …

Rauchgasseitige Korrosion von Nickelbasislegierungen für zukünftige 700C-Dampfkraftwerke
Coal is still the most important energy source in Germany. In 2009 it produced 42.9% of the overall German electrical power. Coal is available world-wide in large quantities and can be delivered economically. One of the possible ways to reduce COB2B pollution is the increase of efficiency of coal …
