25 Years with 20 Tons of Gleeble Power at voestalpine Böhler Edelstahl
Presenter: Dr. Siegfried Kleber Research & Development voestalpine BÖHLER Edelstahl
Abstract: A Gleeble 3800 system has been operated in the research laboratories of Böhler Edelstahl GmbH & Co KG since 1997. This system was the first in the world to be equipped with a hydraulic unit, that can apply a pressure load of up to 20 tons. In the almost 25 years of its use, the most diverse alloys that Böhler produces have been examined and special test programs have been developed. Unique thermomechanical tests, some of which are very special, have contributed significantly to the understanding of the materials examined in relation to their production process.
In particular, material parameters that characterize the hot formability were determined for very high-temperature steels and nickel-based alloys. These are the basis for a further FEM simulation of various rolling and forging processes. Understanding dynamic microstructure changes has always been a central issue for all of the alloys examined.
In summary, it can be said that the Gleeble system has made a significant contribution to increasing product quality and process reliability over this long period. In the webinar, some clear examples are shown how practical test programs were planned and carried out.
