摘要：

Cu-Co-Ni diffusion couples are studied at 1273 K, the composition profiles of which are used to extract interdiffusion coefficients as functions of composition. Such values are further combined with thermodynamic description to extract atomic mobilities of Cu, Co and Ni in order to establish a general Co-based or Ni-based mobility database. The quality of Cu, Co and Ni atomic mobilities are verified through extensive comparisons between calculated and experimentally measured concentration profiles in diffusion couples and diffusion paths in Gibbs triangle.
