👉 Intercrystalline is a term used in the field of crystallography and is defined as a phase that forms within a crystal. It refers to the phase that is present at the interface between two or more crystals, which are typically formed when atoms move from one crystal to another. This process can occur due to a variety of reasons such as cooling, heating, or other mechanical forces acting on the crystal lattice. Intercrystalline phases are often characterized by their unique physical and
