A hierarchically correlated flow defect model for metallic glass: Universal understanding of stress relaxation and creep
(2022-07-01)
Article
Open AccessDue to the structurally disordered arrangement of atoms and deviation from thermodynamic equilibrium, the physical and mechanical properties of metallic glasses can vary with time, temperature and magnitude of strain or ... -
Dynamic mechanical relaxation in LaCe-based metallic glasses: influence of the chemical composition
(Multidisciplinary Digital Publishing Institute (MDPI), 2019-09-17)
Article
Open AccessThe 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 ... -
Effect of minor addition on dynamic mechanical relaxation in ZrCu-based metallic glasses
(2021-02-01)
Article
Open AccessThe dynamic mechanical behavior of Zr50-xCu34Ag8Al8Pdx (x = 0 and 2) bulk metallic glasses was probed by mechanical spectroscopy. The results suggest that microalloying retards the relaxation dynamics. The physical aging ... -
Modelling and physical analysis of the high-temperature rheological behavior of a metallic glass
(2021-11-01)
Article
Open AccessThe high-temperature rheological behavior, around the glass transition temperature, of a Zr48Cu34Ag8Al8Pd2 metallic glass was investigated by strain rate jump experiments. The results show that the plastic deformation ...
