Abstract
Plastic deformability of the binary (copper and zirconium) amorphous alloy with embedded nanosized crystals under uniaxial tension and compression is analyzed using molecular dynamics simulations. The number and the size of the nanocrystals are taken as the study parameters. The number of nanocrystals affects the distribution of defects, that is, shear bands nucleation and thus changes the stress-strain curve, whereas the size of the nanocrystals does not significantly influence the response. As already reported in the experimental works, coalescent voids are found under tension in the shear bands or at the interface between crystalline and amorphous phases. This suggests that much attention should be paid to the interface strength around the particles.
