Abstract	The collaborative research centre SFB 561 “Thermal highresistant open-pore and cooled multilayer systems f or hybrid power stations” is aimed at enhancing the total eff ici ncy of hybrid power stations from the current level of 58% to approx. 65%. This requires the realization of turbine enter i g temperatures of 1,400°C (ISO) in a gas turbine, and involves bot h the investigation of new materials and production proce sses as well as new kind of layered components for transpiration co oling. A main focus in foundry technology is the manufacture of c mponents from highly temperature-resistant NiAl and NiAl com posites. The development of a casting technology for technic ally interesting NiAl-alloys is part of the Foundry-Inst itu e subproject “Casting Technology”. Its aim is the development of a scientific and technological basis for the manufacture of effu sion-cooled gas turbine blades. Due to their high melting temperatu res of approximately 1,640°C, their high thermal conductiv ity and high oxidation resistance at elevated temperatures, NiAl -alloys are well suited as a substitute for superalloys, amongst oth ers, in combustion chamber linings and turbine blades.
