摘要：

Given the critical role of diffusion in material design, particularly its relationship with composition and structure, this study focuses on the diffusion properties in the Co-Fe-X (X=V/Mn) ternary systems, which are key sub-systems of high-entropy alloys. To carefully evaluate the interdiffusivity and atomic mobility for fcc Co-Fe-X (X=V/Mn) phase, annealing is performed at 1273, 1373, and 1473 K on 12 diffusion couples for each ternary system. EPMA (Electron Probe Microanalysis) is used to measure composition profiles after annealing. To provide more reliable diffusion coefficients, atomic m...
