First-Principles Study on Si Atom Diffusion Behavior in Ni-Based Superalloys

First-Principles Study on Si Atom Diffusion Behavior in Ni-Based Superalloys

The Si atom diffusion behavior in Ni-based superalloys was evaluated based on first-principles calculations. Also, the site occupation of Si atoms as the melting point depressant elements in Cr, Mo, and W atom doped γ-Ni and γ′-Ni<sub>3</sub>Fe supercells was discussed and Si atom diffus...
