Abstract
In modern society, metal products are needed in various industries. The annealing process is commonly employed in manufacturing. Based on the specifications of the product, the purpose of annealing is different, the annealing process specification has a variety of commonly used complete annealing, spheroidal annealing, and stress relief annealing. This paper investigates and compares the characteristics of different annealing processes in the production process through the literature research method. This paper describes seven annealing methods, mainly detailing two annealing processes, spheroidizing annealing, and recrystallization annealing, and gives examples of the advantages and disadvantages of these two processes. Annealing is primarily used to improve machinability and reduce hardness. It also stabilizes size, lowers residual stress, and lessens the tendency for deformation and cracking. Cut down on grain, reorganize, and get rid of organizational flaws, even material composition and organization can enhance a material's qualities or prepare it for upcoming heat treatments.
