However, aluminum alloys spontaneously change shape and size, which can affect the accuracy and reliability of aerospace equipment and instruments. Therefore, improving the stability of aluminum alloy structural components is of great significance. To improve the dimensional stability between aluminum alloys, heat treatment is generally used to reduce internal stress. Commonly used heat treatment stabilization methods include isothermal aging, reverse quenching, thermal cycling, deformation heat treatment, and cryogenic treatment. Among these, cryogenic treatment is the most commonly used and effective heat treatment process.
