The slow transition from an out-of-equilibrium glass towards a supercooled liquid is complex relaxation phenomenon. In this Letter, we study the correlation between mechanical and equilibration kinetics in ${\text{Pd}}_{20}{\text{Pt}}_{20}{\text{Cu}}_{20}{\text{Ni}}_{20}{\mathrm{P}}_{20}$ high-entropy metallic glass. evolution of stress with aging time was obtained unprecedented detail, allowing us to pinpoint new interesting features. long structural equilibrium contains wide distribution...
Hydrogen production through hydrogen evolution reaction (HER) offers a promising solution to combat climate change by replacing fossil fuels with clean energy sources. However, the widespread adoption of efficient electrocatalysts, such as platinum (Pt), has been hindered their high cost. In this study, we developed an easy-to-implement method create ultrathin Pt nanomembranes, which catalyze HER at cost significantly lower than commercial Pt/C and comparable non-noble metal...
We developed a facile ultrasonic vibration route is to synthesize BMGs and metallic glass-glass composites.
Lacking the structural information of crystalline solids, origin relaxation dynamics metallic glasses is unclear. Here, we report evolution stress high-entropy with distinct β behavior. The fraction liquidlike zones, determined at each temperature by intensity decay, shown to be directly related both aging process and spectrum modes obtained mechanical spectroscopy. results shed light on intrinsic correlation between static dynamic response in conventional glasses, pointing toward a sluggish...
The short-range ordered but long-range disordered structure of metallic glasses yields strong structural and dynamic heterogeneities. Stress relaxation is a technique to trace the evolution stress in response fixed strain, which reflects features phenomenologically described by Kohlrausch-Williams-Watts (KWW) equation. KWW equation describes broad distribution times with small number empirical parameters, it does not arise from particular physically motivated mechanistic picture. Here we...
Abstract Rejuvenation is the structural excitation of glassy materials, and a promising approach for improving macroscopic deformability metallic glasses. This atomistic study proposes application compressive hydrostatic pressure during glass-forming quenching process demonstrates highly rejuvenated glass states that have not been attainable without pressure. Surprisingly, pressure-promoted rejuvenation increases characteristic short- medium-range order, even though it leads to higher-energy...
It has so far remained a major challenge to quantitatively predict the boson peak, THz vibrational anomaly universal for glasses, from features in amorphous structure. Using molecular dynamics simulations of model Cu_{50}Zr_{50} glass, we decompose peak contributions atoms residing different types Voronoi polyhedra. We then introduce microscopic structural parameter depict "orientational order," using vector pointing center atom farthest vertex its coordination polyhedron. This order...
What determines the glass property remains one of major unsolved problems in both condensed matter physics and materials science. Despite extensive research attempting to identify possible structural features as signatures glasses obeying conventional philosophy ``structure property'' matter, hidden rule about why some proposed structures predict properties effectively but others do not is still poorly understood. Here we revisit earlier successful ``structural descriptors'' glasses, e.g.,...
