High-throughput determination of interdiffusivity in fcc Cu-Al-Sn and Cu-Ni-Al-Sn alloys
Abstract In this paper, 6 Cu-Al-Sn ternary and 8 Cu-Ni-Al-Sn quaternary solid diffusion
couples within single fcc phase from 1023 K to 1173 K were fabricated. Employing the
measured concentration profiles and interdiffusion fluxes, the atomic mobility parameters
and interdiffusion coefficients in Cu-Al-Sn and Cu-Ni-Al-Sn systems were high-throughput
evaluated using the numerical inverse method. The simulated composition distributions and
interdiffusion fluxes in all the diffusion couples are consistent with the measured ones …
