The annealing of a material is a process corresponding to a heating cycle. It consists of a gradual temperature rise followed by controlled cooling. This procedure, common in materials science, allows the physical characteristics of the metal or material under study to be modified. This action is particularly used to facilitate the relaxation of stresses that could have been accumulated in the heart of the material, under the effect of mechanical or thermal stresses, occurring in the synthesis and shaping of materials. During an annealing process, the (single-crystal) grains of material reform and regain their “state of equilibrium”, as it were.
Annealing is also used to change the magnetic properties of a part.
The purpose of crystallisation annealing, after cold working, is to give the metal an optimal grain size for its future use (bending, stamping, etc.).
