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 ...

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 ...

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 ...
