Abstract

This article investigates the material structure and deformation behavior of the Ni70Co30 alloy film on a Ni(001) substrate using the molecular dynamics (MD) simulation method. The simulations performed include deposition, annealing, and indentation. The study also examines the effect of temperature on the structural changes of the alloy film. The results show that higher temperatures lead to a decrease in the force required for indentation. Additionally, increasing temperature enhances the deformation behavior and structural changes of the Ni70Co30/Ni material. Notably, high temperatures influence the formation and development of dislocation in the Ni70Co30 alloy film on the Ni(001) substrate.
