Abstract
This chapter deals with plastic deformation of metallic glasses. Usually, plastic flow in metallic glasses shows an intermittent plastic strain bursts, which correspond to shear-bands formation and propagation, i.e., the so-called shear avalanche. During plastic deformation, the shear–strain burst in metallic glasses is stochastic in spatio-temporal distribution. Accordingly, a statistical analysis combined with dynamic analysis is introduced to characterize the plastic mechanism. The dynamics of the plastic flow in metallic glasses shows a transition from self-organized critical behavior to chaotic behavior due to the changes in loading conditions, environmental temperatures and micro-structures. The influences of the strain-rates, temperatures, geometrical size, and the second phase embedding into the glassy phase on the dynamics of the plastic deformation of metallic glasses are summarized in this chapter.
