| Abstract Scope |
Fast differential scanning calorimetry (FDSC) at heating and cooling rates of several 10,000 K/s to temperatures above the melting of metallic materials has only become recently possible. Applying it to bulk metallic glass (BMG)-forming systems, which reveal sluggish crystallization kinetics, we can explore novel phenomena such as inverse melting and the existence of polymorphic metallic glasses that reveal distinctly different critical cooling rates [1]. We can further study the formation and properties of novel metastable phases [2] and determine their heat capacities and melting temperatures. Here we present our recent correlative FDSC studies, combined with synchrotron X-ray diffraction [3] and electron microscopy, to unravel simultaneously the structure and thermophysical properties of metallic materials and organic compounds.
