Casting-rolling line at TU Freiberg enables innovative magnesium components for lightweight construction


The researchers at the Institute for Metal Forming at the TU Freiberg are able to produce magnesium strips up to 70 centimetres wide with this unique prototype plant. These can be used to produce novel, lightweight magnesium components for the automotive industry or mechanical engineering.

As part of the AMARETO project (Saxon Alliance for Material and Resource Efficient Technologies), the Institute for Metal Forming (IMF) has now produced cast rolled magnesium strip of the alloy WZ73 for the first time worldwide.

Under the supervision of the experienced machine master Jürgen Ljunggren, belts are produced under stable process conditions.

This is not only extremely light, but also very stable and recyclable. This makes it particularly interesting for the lightweight construction industry. The scientists are currently carrying out further tests on the 60 panels produced. The aim is to further optimize the process parameters.

"This achievement proves the versatile application of the pilot plant at the IMF. With our new, young research team, we want to advance and further develop the forward-looking technology of casting-rolling", says IMF Director Prof. Ulrich Prahl. The planned research tasks include the use of different alloys, optimized machine components and innovative measuring technology.

Thorsten Henseler's new "casting-rolling team" is focusing on the comprehensive digitalization of the process: "The potential to gather new findings for science and industry in this way is enormous. Above all, we see many potential uses for the future of industry 4.0 in the rapid analysis of newly acquired process data".

To the AMARETO project:

In the "Saxon Alliance for Material- and Resource-Efficient Technologies - AMARETO", which is funded by the Saxon State Ministry of Science and the Arts with 5.5 million euros, institutes of the Technical Universities of Freiberg, Chemnitz and Dresden and the Fraunhofer IWU are pooling their expertise with the common goal of developing new methods and transfer solutions for individual parts of the value-added chain that will enable SMEs to significantly reduce their product launch risk.

Im Focus: New measurement exacerbates old problem

Two prominent X-ray emission lines of highly charged iron have puzzled astrophysicists for decades: their measured and calculated brightness ratios always disagree. This hinders good determinations of plasma temperatures and densities. New, careful high-precision measurements, together with top-level calculations now exclude all hitherto proposed explanations for this discrepancy, and thus deepen the problem.

Hot astrophysical plasmas fill the intergalactic space, and brightly shine in stellar coronae, active galactic nuclei, and supernova remnants. They contain...

Im Focus: Biotechnology: Triggered by light, a novel way to switch on an enzyme

In living cells, enzymes drive biochemical metabolic processes enabling reactions to take place efficiently. It is this very ability which allows them to be used as catalysts in biotechnology, for example to create chemical products such as pharmaceutics. Researchers now identified an enzyme that, when illuminated with blue light, becomes catalytically active and initiates a reaction that was previously unknown in enzymatics. The study was published in "Nature Communications".

Enzymes: they are the central drivers for biochemical metabolic processes in every living cell, enabling reactions to take place efficiently. It is this very...

Im Focus: New double-contrast technique picks up small tumors on MRI

Early detection of tumors is extremely important in treating cancer. A new technique developed by researchers at the University of California, Davis offers a significant advance in using magnetic resonance imaging to pick out even very small tumors from normal tissue. The work is published May 25 in the journal Nature Nanotechnology.
