Abstract Molecular dynamics (MD) simulations were used to study the effect of the crystallographic orientation of B2-CuZr nanocrystals on the mechanical properties and plastic deformation behavior of B2-CuZr nanocrystal/Cu₅₀Zr₅₀ amorphous composites under axial stretching. In the simulations, the EAM potential function was used to express the interatomic interactions. The calculation results show that the B2-CuZr nanocrystal/Cu₅₀Zr₅₀ amorphous composites with crystallographic orientation [110] can form interlocking shear bands under the load, and the yield strength is improved, showing a good plastic flow; while the plasticity of the composites with crystallographic orientation [100] and [111] does not get improved significantly, the composites with crystallographic orientation [111] have the highest yield strength and the largest elastic modulus; the composites with crystallographic orientation [100] have the smallest elastic modulus, which is comparable to Cu₅₀Zr₅₀ amorphous. The elastic modulus of nanocrystalline/amorphous composites with a crystallographic orientation of [110] lies between the above two and presents overall more excellent overall mechanical properties.
