This study aims at investigating the underlining mechanism and kinetics of the selective dissolution of Ni from Inconel 718 (one type of Ni-based superalloy) with liquid Mg, by experimenting at 750, 800, and 850 °C for various amounts of time in an inert atmosphere.

Results show that a permeable dealloyed layer was formed resulting from the preferential dissolution of Ni over other metallic elements (e.g., Fe, Cr, Nb, Mo, and Ti). At the dealloying forefront, the grain boundaries of the matrix γ phase were preferentially eroded by liquid Mg. The opposite concentration gradients of Ni (4–9 wt%) and Mg (12–18 wt%) cross the dealloyed layer suggested their counter diffusion.
