|Abstract:||The electrochemical Dy-alloying behaviors of Inconel 600 and Hastelloy C-276 were investigated in a molten LiF–CaF₂–DyF₃ (0.30 mol%) system at 1123 K. Cyclic voltammetry and open-circuit potentiometry suggested the formation of several phases of Dy–Ni alloys. Potentiostatic electrolysis was conducted to prepare alloy samples using Inconel 600 and Hastelloy C-276 plate electrodes at 0.20 V vs. Li⁺/Li for 60 min. Cross-sectional scanning electron microscopy revealed that Dy–Ni alloys were formed in both samples. X-ray diffraction analysis confirmed the formation of DyNi₂ as the predominant phase for both the samples. Phase separation of the alloy layer into the DyNi₂ phase and formation of the agglomerated Cr–Fe and Cr–Fe–Mo phases were indicated by EDX mapping analysis.|
