TL;DR: It is shown that the structural relaxation processes underlying aging in this metallic glass are intermittent and highly heterogeneous at the atomic scale, and physical aging is triggered by cooperative atomic rearrangements, driven by the relaxation of internal stresses.

TL;DR: In this article, 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 calorimetry, thermomechanical testing, and x-ray photon correlation spectroscopy.

TL;DR: In this article, the authors investigated liquid Ge15Te85 spanning a wide temperature range from near Tg to the melt, and demonstrate that the density anomaly and fragile-strong transition are not only related to short-range-order structural change (e.g. Peierls-like distortion), but also accompanied by a remarkable development of medium-range order (MRO).

TL;DR: In this paper, the authors investigated the thermodynamic and kinetic properties of Pt-P- and Ni-P based bulk glass-forming liquids using differential scanning calorimetry and three-point beam bending.

TL;DR: In this paper, the authors used the classical nucleation theory to model the isothermal crystallization data for Pt 42.5 Cu 27 Ni 9.5 P 21 and the Pt 60 Cu 16 Co 2 P 22 bulk glass forming compositions using calorimetric experiments.
