Although the atomic structure of amorphous alloys, which lacks long-range translational
symmetry, may appear homogeneous at the macroscopic scale, their local dynamic and/or …

Dynamic relaxation is an intrinsic and universal feature of glasses and enables fluctuation
and dissipation to occur, which induces plentiful behaviour, maintains equilibrium, and …

Lacking the structural information of crystalline solids, the origin of the relaxation dynamics
of metallic glasses is unclear. Here, we report the evolution of stress relaxation of high …

Complex materials are composed of basic units which invariably interact with anharmonic
potentials. It is well known that the dynamics of systems with anharmonic interaction are …

The slow transition from an out-of-equilibrium glass towards a supercooled liquid is a
complex relaxation phenomenon. In this Letter, we study the correlation between …

Metallic glasses have aroused considerable interest in the past decades because they
exhibit fascinating properties. First, this article briefly outlines the mechanical, thermal …

Focusing on metallic glasses as model systems, we review the features and mechanisms of
the β-relaxations, which are intrinsic and universal to supercooled liquids and glasses, and …

Understanding and controlling physical aging, that is, the spontaneous temporal evolution of
out-of-equilibrium systems, represents one of the greatest tasks in material science. Recent …

Non-equiatomic high entropy bulk metallic glasses were reported recently and show unique
mechanical and physical properties. Dynamic mechanical relaxation behavior of Zr 35 Hf …

Still very little is known on the relaxation dynamics of glasses at the microscopic level due to
the lack of experiments and theories. It is commonly believed that glasses are in a dynamical …
