Abstract: Abstract The change of physical properties during aging and the associated microscopic dynamics of the Au49Cu26.9Si16.3Ag5.5Pd2.3 bulk metallic glass are investigated using a broad collection of laboratory and synchrotron-based techniques, such as differential- and fast-scanning… read more here.

Abstract: In this work, we revisit the fragile-to-strong transition (FTS) in the simulated BKS silica from the perspective of microscopic dynamics in an effort to elucidate the dynamical behaviors of fragile and strong glass-forming liquids. Softness,… read more here.

DOI: 10.1103/physrevmaterials.2.115604
Abstract: Many bulk-metallic-glass (BMG) forming melts undergo a rather abrupt fragile-to-strong transition (FST), at which density and local structure appear to change only continuously. In this study, we reproduce similar results for a ternary BMG former… read more here.
