Figure 3. Theoretical and experimental results for the Cu-W system: (A) calculated equilibrium phase diagram; (B) ln(rD) vs. 1000/Tc plot with phase boundary data from the experimental metastable phase formation diagram; (C) 3D atom-probe tomography data of Cu0.57W0.43 coating with the reconstructed needle and proxigram analysis of the composition; and (D) first-principles calculated diffusion activation barriers compared with experimental values.
