Analyzing the synergistic impact of hydrogen and structural defects on nickel's mechanical and diffusion characteristics

Key Points

• The research aims to explore how hydrogen atoms interact with structural defects in nickel and affect its properties.
• Conducted molecular dynamics simulations to assess the impact of hydrogen on nickel.
• Focused on the roles of vacancies and self-interstitial atom defects.
• Analyzed H diffusion and mechanical characteristics under different defect scenarios.
• Hydrogen significantly influences the diffusion rates of atoms within nickel.
• Structural defects alter nickel's mechanical properties, enhancing or reducing its strength.
• The combination of hydrogen and defects creates a synergistic effect on material behavior.
