Exploration of fast time scales in metallic glasses and reactive metallic multilayers by chip calorimetry

Understanding the nature of transitions between the glassy, liquid and crystalline states is a major challenge in physics as well as in materials science. With the emergence of advanced fast calorimetry, based on a chip-technology, we can nowadays access shorter and shorter time scales and thus experimentally measure the thermophysical properties of materials far from equilibrium. In this talk, we build on established and new work that our group has performed with this technique at ultra-short time scale for the study of many material characteristics. Selected topics may include: TTT-diagrams near the nose for crystallization [1], study of the undercooled liquid and glass formation from the melt in metallic glass-forming systems [2,3,4], hierarchical physical aging in bulk metallic glasses
