“…(1) There exists a controversy about the effect of cyclic loading on microstructure of MG [39][40][41][59][60][61][62][63][64]. That is, the cyclic loading may induce the structural relaxation or rejuvenation, and nanocrystallization.…”

The fatigue damage and fracture of metallic glasses (MGs) were reported to be dominated by shear band. While there exist several reviews about the fatigue behavior of MGs, an overview that mainly focuses on shear bands under cyclic loading is urgent, and is of great importance for the understanding of fatigue mechanisms and properties. In this review paper, based on the previous research results, the shear band evolution under cyclic loading including shear band formation, propagation and cracking, was summarized and elucidated. Furthermore, one strategy of enhancing the fatigue property through manipulating the microstructure to suppress the shear band formation was proposed. Additionally, the applications of the effect of annealing treatment and processing condition on fatigue behaviors were utilized to verify the strategy. Finally, several future directions of fatigue research in MG were presented.

“…The MD simulation of cyclic loading in a CuZr system indicated that the structural rejuvenation is associated with the nucleation and development of shear events in the bulk of MG 29 . Louzguine-Luzgin et al 30 demonstrated that the room-temperature cyclic loading up to 0.4% of elastic strain may induce the nanocrystallization in the amorphous material. Employing a kind of cyclic loading, i.e.…”

Structural rejuvenation is one of the key topics in the field of metallic glasses (MGs). In this work, we evaluated the combined effects of annealing treatment and elastic cyclic loading to discover pathways for promoting structural rejuvenation and improving the mechanical properties in the MGs. Using molecular dynamics (MD) simulations, it was revealed that the sole cyclic loading led to the increase of rejuvenation degree; however, a saturated state was observed upon the 40 th cycle. On the other side, the sample exposed to the combined treatment exhibited a slight relaxation at the first step of cycling process and then a sharp rejuvenation degree was detected in the material. The thorough analyses indicated that the change in the fraction of coordination polyhedrons at the relaxation stage was the main reason for the extra rejuvenation in the sample exposed to the combined treatments. The results also suggest that the combination of rejuvenation treatments improves the magnitude of rejuvenation in the amorphous alloys. It should be noted that the increase of rejuvenation in the alloying systems accompanied with a reduction in the tensile strength and an enhancement in the homogenous plastic deformation.

“…Along with corrosion [ 13 ] and magnetic [ 14 ] properties, mechanical parameters of different amorphous alloys (AMA) have been intensively investigated [ 15 ] since the first synthesis of metallic glass (MG) [ 16 ]. As these materials have some quantitative advantage by the mentioned properties, analysis of their behavior is more actual for the industry [ 17 ].…”

In this work, derivation of the main thermodynamic relationships is realized together with the applied calculation of some parameters, providing the systematized description of non-linear thermo-mechanical deformation at dynamic mechanical analysis (DMA). Obtained equations and values agree well with experiments on different ribbon metallic glasses. We generalize the main initial conditions (i.e., experimental and numerical parameters) by that the proposed model can be used for the investigation of DMA in different materials. The further opportunities of the found approach are also discussed in frames of phase transitions in metallic glass.
