(a) Arrhenius plots of Ni GB diffusion in CoCrFeNi (circles) and CoCrFeMnNi (squares) measured in B- (the P values, solid symbols) and C-type (the δ·D gb values, open symbols) kinetic regimes. The values of the Ni GB diffusion coefficients are multiplied by the GB width δ taken as 0.5 nm. (b) Comparison of GB diffusivities (triple products) of Ni in CoCrFeNi and CoCrFeMnNi alloys with pure Ni27 and Fe-Ni alloy32 against the inverse of the absolute temperature.
