摘要：

The accurate diffusivity and kinetic database of fcc quinary Cu-Co-Mn-Ni-Si system is essential for designing high-performance Cu alloys, which is still not investigated yet. In the present work, on the basis of the critically reviewed experimental diffusivities available in the literature, the atomic mobilities of fcc Mn-Ni and Cu-Mn-Ni alloys were re-assessed through CALTPP (CALculation of ThermoPhysical Properties) program, aiming to establish a self -consistent kinetic database for fcc Cu-Co-Mn-Ni-Si system. Comparing the model-calculated diffusion coefficients, composition profiles and di...
