Microstructure of Inconel 625
625 features a face-centered cubic lattice structure. After being held at approximately 650℃ for a sufficient duration, carbon particles and unstable quaternary phases will precipitate and transform into a stable Ni3(Nb,Ti) tetragonal lattice phase. Post solid solution strengthening, the molybdenum and niobium components in the nickel-chromium matrix will enhance the material's mechanical properties, although plasticity will be slightly reduced.
