Intermetallics Disappearance Rates and Intrinsic Diffusivities Ratios Analysis in the Cu-Zn and the Cu-Sn Systems

Abstract

Intermetallics disappearance rates and intrinsic diffusivities ratios in the Cu-Zn system at temperature 400oC and in the Cu-Sn system at temperatures from 190oC to 250oC are analyzed theoretically using literature experimental data. Diffusion activation energies and pre-exponential coefficients for Cu-Sn system are calculated combining literature experimental results.
