Understanding mechanical relaxation, such as primary (a) and secondary (ß) relaxation, is key to unravel the intertwined relation between the atomic dynamics and non-equilibrium thermodynamics in metallic glasses. At a ...

Dynamic mechanical relaxation is a fundamental tool to understand the mechanical and physical properties of viscoelastic materials like glasses. Mechanical spectroscopy shows that the high-entropy bulk metallic glass ...

The mechanical relaxation behavior of the (La0.5Ce0.5)65Al10(CoxCu1-x)25 at% (x = 0, 0.2, 0.4, 0.6, and 0.8) metallic glasses was probed by dynamic mechanical analysis. The intensity of the secondary ß relaxation increases ...

The power-law relationship between creep rate decay and time is one of the intrinsic characteristics of metallic glasses. In the current work, a La30Ce30Ni10Al20Co10 high-entropy metallic glass was selected as the model ...

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-entropy metallic glasses with ...

Mechanical relaxation of glassy materials is strongly influenced by their mechanical and physical properties. In the current study, dynamic mechanical relaxation of Cu46Zr46Al8 metallic glass has been investigated by ...

Dynamic mechanical relaxations of La-based metallic glasses were investigated by mechanical spectroscopy. In the framework of the mixing enthalpy of constituent atoms, it was found that ß relaxation was less evident by the ...

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 static properties however vary significantly ...

Dynamic mechanical relaxation, stress relaxation and creep were performed in a La56.16Ce14.04Ni19.8Al10 metallic glass with pronounced relaxation features. The evolution of the microstructural heterogeneity with temperature ...
