Pressure and heat: Testing alloys for gas turbines

Gas turbines must endure extreme conditions like high forces at temperatures above 600°C. Gas turbine materials therefore must be sufficiently robust, and as such they are under constant development. Together with the Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU), VDM Metals International GmbH tested its improved VDM Alloy 780 using a specially developed testing machine at the Research Neutron Source Heinz Maier-Leibnitz (FRM II).

Metals with memory

When metallic objects change their shape seemingly without any external influence and only according to the will of their owners, this at first sounds like something only comic superheroes like Magneto and Ironman could do. However, the idea from those comics has a real-world manifestation in existing materials called magnetic shape memory alloys (MSMAs). Moreover, they have potential applications e.g. in robotics or medical devices.

Hydrogen and alternative energy vectors Science Highlights

When hydrogen glows red

A team of German and Dutch scientists synthesised a series of substances, which show bright luminescence under UV light. Therefore the amount of hydrogen in the structure determines the wavelength – and hence the color – of the emitted light. These compounds could be used as illuminants in LEDs or for chemical hydrogen storage.
