Atomic Process Annealing occurs by a solid-state diffusion, so that the material progresses towards its equilibrium state. Heat is needed to increase the rate of diffusion by providing the energy needed to break bonds. The movement of atoms has the effect of redistributing and destroying the dislocations in metals. This alteration in dislocations allows metals to deform more easily, so to increases their ductility. Amounts of internal strain (level of cold work) within the crystalline lattice also play a important role to initiate the recovery process.
