Abstract

The effect of microstructural inhomogeneities with different length scale on the plasticity of (Ti₄₅Zr₁₆ Be₂₀CU₁₀ Ni₉)_100-x Ta_x (x = 0,5, and 10) bulk glassy alloys has been studied. The formation of specific heterogeneous microstructures with a different type of structural inhomogeneity, i.e., short-/medium-range ordered clusters or micrometer-scale ductile dendrites combined with a glassy matrix, evolved by appropriately tuning the alloy chemistry, improves the room temperature plasticity up to -12.5% and -15%, respectively. The pronouncedly enhanced plasticity is mainly attributed to the retardation of shear localization and multiplication of shear bands by controlling the plastic and failure instabilities otherwise responsible for premature failure.
