中文摘要	Quasi-static compressive behaviors of three amorphous alloys (Cu50Zr50, Pd80Si2O, and Ni67Zr33) are investigated via molecular dynamics simulations. Compared to the crystalline counterpart, when the strain is below 1%, significant fluctuations can be observed in the stress-strain curves. Further analysis of the simulated data indicates that the fluctuations are associated with the variations of Voronoi volume. A gradient reduction model is proposed to explain the process of the evolution of Voronoi volume at the initial stage of the deformation. (C) 2014 AIP Publishing LLC.
