An indispensable treatment method in the production of 2A12 aluminum plate is aging, so we all know that aging treatment of 2A12 aluminum plate is relatively common, next 2A12 aluminum plate manufacturer would like to introduce to you, 2A12 aluminum plate aging hardening principle.

Aging hardening is a complex process, which is mainly affected by the composition and aging process of 2A12 aluminum plate, and the defects caused in the production process of 2A12 aluminum plate, especially the number and distribution of vacancies and dislocations, will also be affected.Solute atoms are formed into hardened zone by partial agglomeration, which is the product of aging hardening.

When the 2A12 aluminum plate is quenched and heated, vacancies are formed in the alloy. During quenching, however, when the cooling is fast, the vacancies have no time to move out, and are "fixed" in the crystal. Most of the vacancies are combined with solute atoms.Vacancy has the characteristics of susaturated solid solution, and its characteristic plant is in an unstable state, which will accelerate the diffusion rate of solute atoms and the partial polymerization of solute atoms.

Quenching temperature and quenching cooling speed are affected by the size and number of hardening zone.At higher quenching temperature, the larger the vacancy is, the more the number of hardened areas is, and the size of hardened areas will decrease.Increasing the number of hardened zones and decreasing the size of hardened zones are mainly due to the fact that the greater the quenching cooling speed is, the more vacancies fixed in the solid solution will be.
