TL;DR: In this paper, a two-dimensional cold rolling was performed on a bulk metallic glass (BMG) with composition Zr 58.5 Cu 15.6 Ni 12.8 Al 10.3 Nb 2.8.

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, in situ structural analysis of a bulk metallic glass forming liquid was performed using high energy synchrotron x-ray radiation combined with electrostatic levitation, and the data indicated a liquid-liquid transition (LLT) in the deeply undercooled state at $T/{T}_{g}ensuremath{\sim}1.2$ which manifests as a maximum in the heat capacity and an abrupt shift in the first peak position of the total structure factor in the absence of a pronounced density change.

TL;DR: In this paper, the thermal decomposition behavior, microstructural evolution and its influence on the mechanical properties of a supersaturated Cu-Co solid solution with ∼100nm average grain size prepared by severe plastic deformation was investigated under non-isothermal and isothermal annealing conditions.
