Diffusive Phase Transformation

Diffusive phase transformation is a process where the structure of a metal or alloy changes gradually through the movement of atoms. During this transformation, atoms diffuse—or migrate—over time, allowing the material to shift from one phase (or state) to another, such as from liquid to solid or between different solid structures. This process is driven by differences in energy and stability, and it typically occurs slowly, enabling the material's properties to evolve smoothly. It's fundamental in manufacturing and materials science because controlling these transformations helps tailor the material’s strength, hardness, and other characteristics.
