P. Estermann:
"Necessity is the Mother of Invention: Creative Approaches with a 40 year old Gleeble to Better Understand Continuous Casting of Steel";
Talk: Gleeble Webinar Series, Episode 44, Online (invited); 2021-09-23.

The Institute of Materials Science and Technology has been utilizing the same Gleeble for hot tensile tests and occasional compression tests for over 40 years. Several PhD students performed their experiments, changed parameters as well as geometries and added attachments to the machine. A common theme throughout the years is the investigation of hot ductility of different steel grades. The ductility minimum affects certain steels significantly and in turn causes problems during the straightening step of the continuous casting process. Several mechanisms have been found to embrittle the grain boundaries of steel and test setups have been devised to pinpoint them.

In this talk, Paul Estermann will review some of the setups and sample geometries used, along with findings obtained from the experiments. Both previous research as well as ongoing experiments will be presented to show the versatility of the Gleeble system. Paul and his team use the machine not only for complex thermo-mechanical sequences but also to put the samples into defined precipitation states for further analysis.
