摘要

Al₈₅Ni₅Y_10-xCo_x (x=0, 2) and Cu₄₆Zr_54-xAl_x (x=0, 7) metallic glasses (MGs) have been examined using fluctuation electron microscopy (FEM). Strong medium-range order (MRO) was revealed in both MG systems. Minor additions of Co into the Al₈₅Ni₅Y₁₀ and Al into the Cu₄₆Zr₅₄, forming Al₈₅Ni₅Y₈Co₂ and Cu₄₆Zr₄₇Al₇ MGs, render the medium-range structure more homogeneous. This is in a good agreement with the increase of glass-forming ability in these two systems.
