Atomic-scale understanding of the effects of Cr and Ti on γ′ growth kinetics in the Ni–Al-X ternary system: Diffusion couple technique and DFT study

Atomic-scale understanding of the effects of Cr and Ti on γ′ growth kinetics in the Ni–Al-X ternary system: Diffusion couple technique and DFT study

Cr and Ti are essential elements in Ni-based superalloys for γ solid solution strengthening and γ′ precipitation strengthening, respectively, enhancing high-temperature performance. Despite the known benefits of high concentrations, the effects of lower Cr and Ti concentrations on γ′ precipitation k...
