Abstract

The systematic investigation on deformation behaviors between a Ti₄₅Zr₅Cu₄₀Ni_7.5Sn _2.5 BMG containing nano-scale heterogeneity and micron-scale amorphous Zr₆₂Cu₁₇Ni₁₃Al₈ particle-reinforced Cu₅₄Zr₂₂Ti₁₈Ni₆ BMG reveals that an existence of the heterogeneity plays an important role to control the plasticity of the BMGs leading to multiplication of the shear bands. In contrast, the work hardening ability of the BMGs is strongly related to the size of the heterogeneity causing the different shear oscillations during the propagation of the shear bands.
