✦ Synopsis

The study of compositional dependence of Poisson's ratio and compressive plasticity in a CuZr-based bulk metallic glass (BMG) forming system demonstrates that the plasticity of the BMGs is very sensitive to the change of composition. The sensitivity can be well characterized by the Poisson's ratio. The Poisson's ratio and plasticity have a homologous evolution with regard to the adjustment of composition in the alloys. The work has implication that the correlation between the Poisson's ratio and plasticity might provide useful guideline for the development of plastic BMGs in known or unknown BMG-forming alloys.
