New materials for gas turbines of the future

09.09.2008
BAM at the MSE Materials Science and Engineering in Nürnberg

applications for power stations and airplanes have to meet increasingly high demands on system efficiency. The materials used must be absolutely safe and reliable under extreme thermal and mechanical loads. The BAM Federal Institute for Materials Research and Testing carries out research to achieve this objective.

Turbine blades made from titanium aluminides

BAM's investigations now cover turbine blade materials made from an intermetallic titanium aluminide alloy (TiAl). Such alloys have very high tensile strength and a reasonable toughness at high temperatures, light weight, extraordinary corrosion resistance, and the ability to withstand extreme temperatures. Previously, turbine blades were made from nickel alloys with a relatively high specific weight. Aeroplane engines have to maintain their full strength at very high operating temperatures and TiAl alloys materials fulfil this requirement.

BAM is investigating the material properties of new TiAl turbine blade alloys in a research project sponsored by the German Research Foundation (DFG). The materials are exposed to a combination of thermal load and mechanical load. The material behaviour must be characterized under complex loads so that the design engineers can develope components using computer models. The objective of the project is to enable engines to use titanium alloy TiAl turbine blades safely and reliably in practice.

Coating of turbine materials for power stations

Electric power stations equipped with gas turbines are operated at high gas temperatures. Heavy-duty turbine blades are cooled from the inside and are coated with a thermal protection system on the outside.

Supported by the DFG, BAM examines and develops alumina coatings for oxidation and hot corrosion protection of nickel-based alloys. The objective is to develop efficient coating processes in order to supplement existing thermal protection systems or open up new applications.

BAM will present the results at MSE Materials Science and Engineering Congress and Exhibition, which will take place in Nuremberg between 1 and 4 September 2008 (www.mse-congress.de).

Im Focus: Dresdner scientists print tomorrow’s world

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.

The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Im Focus: Three Magnetic States for Each Hole

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".

Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
