Abstract Scope |
Recent developments in detector technology for X-rays generated by high-brilliance synchrotron sources allow for a significant increase in time resolution in experiments involving rapid heating and cooling of alloys. Furthermore, the development of chip-based calorimetry has allowed to reveal several interesting phenomena in metallic glasses, such as metastable melting and subsequent crystallization of intermediate phases. In this talk, we will report our results obtained at beamline P21.2 at DESY in Hamburg to combine these interesting techniques in an in-situ setup to study Fe-based metallic glasses at elevated temperatures. Challenges include size limitations of the beamline setup, insufficient or too high flux, and issues related to the synchronization of calorimeter and beamline. The results reveal time-temperature-transition information at the structural level that can be related in-situ to the calorimetric signal, both measured on very short timescales. |
