The recently developed Arrhenius formula of modified Sutherland equation was applied to calculate the self- and impurity diffusivities in liquid Al, Ce and Ni. Based on the measured tracer and chemical diffusivities available in the literature together with the reliable thermodynamic parameters of the liquid phase in the Al–Ce–Ni system and the atomic mobilities of binary Al–Ni melts, the atomic mobilities...
Based on critically reviewed experimental diffusion data available in the literature, atomic mobilities of Fe, Si, Cu and Zn in bcc_A2 Fe–Cu, Fe–Si and Fe–Zn alloys were assessed as a function of temperature and composition by means of DICTRA simulation package. Semi-empirical correlations were used to obtain the self-diffusivities of Cu, Si and Zn in the metastable bcc_A2 phase. Comprehensive comparisons...
Based on various kinds of experimental diffusivities and thermodynamic parameters available in the literature, the atomic mobilities of Al and Cu in face-centered cubic (fcc) Al–Cu alloys have been assessed as a function of temperature and composition by means of DIffusion Controlled TRAnsformation (DICTRA) software package. Comprehensive comparisons between the calculated and measured diffusivities...
