However, short-range diffusion in the layered structure zones led to different chemical composition among different phases (δ, γ and σ), such that the electrical potential of each phase is different. Therefore, it is easy to etch the layered structure in 310S-WM after PWHTs using relatively weak acid (Kalling’s reagent). Reagents P.O.
