Abstract The investigation on metallic glasses can be dated back to 60 years ago, mainly on exploring ways to realize bulk metallic glasses and understanding their physical properties. In this review paper, we summarized the mechanical properties of bulk metallic glasses under different loading conditions, including tension/compression, micropillar compression, bending, torsion-tension, fracture, and fatigue. In particular, we presented cutting-on-edge analysis on the deformation behavior associated with aforementioned loading conditions: the 2% elastic limit, the spiral fracture, the anomalous notch strengthening, and the Poisson's effect during bending tests, as well as the suitable strength criterion for metallic glasses. At the end, we showed current research on the correlation between plasticity and atomistic structures in metallic glasses. The review paper might be of interest to the solid mechanics society with a focus on the deformation and mechanical properties of advanced materials.
