Inconel 625 microstructure
625 features a face-centered cubic lattice structure. After sufficient holding time at about 650°C, carbon particles and unstable tetragonal phases will precipitate and transform into a stable Ni3(Nb,Ti) trigonal lattice phase. Post-solution strengthening, the molybdenum and niobium content in the nickel-chromium matrix will enhance the material's mechanical properties, although plasticity will decrease.
