Abstract

Abstract: In order to establish a general Ni-based mobility database, diffusion couples for Ni–Fe–Ti ternary systems are prepared, all of which are annealed at 1573 K for 50 h. Interdiffusion coefficients are retrieved from the common compositions of two independent diffusion paths, which are then combined with thermodynamic description to inversely explore atomic mobilities of Ni, Fe and Ti around the Ni-rich region. Good agreements are obtained from comprehensive comparisons between calculated and experimental diffusion coefficients and concentration profiles, which can be used to verify the quality of atomic mobilities obtained in this work.
