Resumen
Thermal treatments include various heating and cooling processes of the material to effect structural changes in it, which modify its crystalline structure and in turn its mechanical and physical properties. The objective of heat treatments is to provide materials with specific properties suitable for their conformation or final use according to the required design and engineering specifications. It is important to clarify that in some cases they modify the chemical composition of the materials in addition to other factors such as the structural constituents and the granulometry, and as a consequence, the mechanical properties (traction, hardness, impact resistance, among others). Heat treatments can be performed on part or all of the piece in one or several steps of the manufacturing sequence. In some cases, the treatment is applied before the forming process (annealing to soften the metal and help it form more easily while hot). In other cases, it is used to alleviate the effects of strain hardening and, if required, can be done late in the manufacturing sequence to achieve strength and hardness.
