Molecular dynamics simulations are presented which provide a detailed picture of the deformation behavior and mechanism of
Cu64Zr36 composite structures reinforced with B2 CuZr nanowires.
When nanowires are distributed in the glassy matrix along the deformation direction, a two-steps stress-induced martensitic transformation is observed.
Since the martensitic transformation is driven by the elastic energy release the formation of a critical shear band is retarded and,
as a consequence, the plasticity of the composite metallic glass is enhanced when compared with the monolithic phase.
Here we provide a general view on the interplay of nanowires transformation and distribution and mechanical properties of composite materials.
Our results suggest that the plasticity of CuZr composite materials can be tailored by carefully choosing the density and spatial distribution of B2 crystalline nanowires.
