| Summary: | In the present work, the interdiffusion coefficients in fcc Cu-Fe-Mn alloys
were experimentally determined via a combination of solid/solid diffusion
couples, electron probe microanalysis (EPMA) technique and Matano-Kirkaldy
method. Based on the reliable thermodynamic description of fcc phase in the
Cu-Fe-Mn system available in the literature as well as the ternary diffusion
coefficients measured in the present work, the atomic mobilities in fcc
Cu-Fe-Mn alloys were assessed by utilizing the DICTRA (Diffusion Controlled
TRAnsformation) software package. The calculated interdiffusion coefficients
based on the assessed atomic mobilities agree well with most of the
experimental data. The comprehensive comparison between various
model-predicted diffusion properties and the measured data, including the
concentration penetration profiles, interdiffusion flux profile, and
diffusion paths, further verify the reliability of the presently obtained
atomic mobilities. |
