At the center of the event from 12 November was the presentation by Prof. Dr. Isabella Gallino (TU Berlin). Under the title “Exploration of fast time scales in metallic glasses and reactive metallic multilayers by chip calorimetry,” she highlighted new experimental opportunities for studying extremely rapid thermal processes. Chip calorimetry enables measurements on the micro- to millisecond scale, opening access to kinetic phenomena that are difficult to capture with conventional methods. Prof. Gallino demonstrated how this technique can be applied to quantify relaxation processes in metallic glasses as well as reaction kinetics in reactive metallic multilayers.

Participants received a clear overview of how chip-calorimetric data can be integrated into thermodynamic models and which opportunities arise for the further development of CalPhaD-based approaches. The presentation also offered practical perspectives for researchers aiming to incorporate novel thermal characterization methods into their own work.

The concluding discussion reflected the high level of interest in the topic. In particular, the potential link between high-speed calorimetry and model-driven materials development sparked lively questions. Many participants emphasized the value of the Coffee Lecture as a space for open exchange and fresh impulses for the CalPhaD community.

The DGM is pleased with the positive response and will continue the series on 10.12.2025 to further strengthen the dialogue on methodological innovation in thermodynamics.
