Abstract

By modifying the cooling rate, a Cu₅₀Zr₄₅Ti₅ alloy with various structures was developed. A fully glassy rod and specimens with different sizes and volume fractions of nanocrystals were produced. The relationship between the structure and mechanical properties of the Cu₅₀Zr₄₅Ti₅ alloy was investigated. The different structures result in a transition of the deformation mechanism from being dominated by shear banding to being governed by dislocation action accompanied by shear band formation. These different plastic deformation mechanisms were discussed in the framework of self-organized critical behavior.
