Two research projects at TU Bergakademie Freiberg placed among the top ten at this year's Steel Innovation Awards, which was presented in the presence of the Federal Minister of Economic Affairs and Energy, Mr. Peter Altmaier, at the “Berliner Stahldialog” (Berlin Steel Conference) on June 13.

According to the German Steel Centre, Germany is the largest steel producer in the EU and the seventh-largest steel producer in the world. At some 17.2 billion euro, the steel industry in Germany accounts for around 30 percent of the value added in the steel industry in Europe. Steel is also a topic of research at TU Bergakademie Freiberg. Among this year's 561 entries to the Steel Innovation Award, two projects in the category “Steel in Research and Development” were among the ten best entries.

“High-strength sheet steel for heat exchangers”

The Awardees.One of the projects is funded by the Federal Ministry of Education and Research under the leadership of Prof. Dr. Andreas Weiß at the Institute of Iron and Steel Technology at TU Bergakademie Freiberg. As part of this project, Christina Schröder's team developed a more cost-effective form of stainless steel. The new metal is stronger and, at the same time, more ductile than conventional stainless steels. This means that in production processes, for example, savings can be made amounting to approximately a quarter of the material normally required. Furthermore, only half of the normal quantity of nickel – an expensive alloying element – is required, which also reduces the risk of contact allergies. A patent is currently pending for the steel, the process for its production in the form of thin sheet metal, and its application. The developers are Technical University Bergakademie Freiberg (the Institute of Iron and Steel Technology), DBI Gas- und Umwelttechnik GmbH, WÄTAS Wärmetauscher Sachsen GmbH, and GESMEX GmbH.

The group’s project was evaluated in the category Steel in Research and Development, and also placed among the top ten. The research group is working on the further development and optimization of the magnetic properties of highly silicified non-grain-oriented electrical steel components used in electric drives and generators. In order to increase their efficiency, the researchers examined the entire process chain experimentally, and developed modeling strategies with the aim of producing an improved material.
