What is annealing process in aircraft materials?

Annealing is a heat treatment process used in the aerospace industry to alter the properties of aircraft materials. It involves heating the material to a specific temperature and then cooling it slowly to achieve desired characteristics such as increased ductility and reduced hardness. Annealing helps to relieve stress and remove internal inconsistencies within the material, which may have been caused by previous machining or forming processes. This process is particularly important for aircraft materials as it enhances their structural integrity and provides them with the necessary strength to withstand the harsh conditions experienced during flight.
