Metal rigging product heat treatment classification
General heat treatment is a heat treatment method that simply uses temperature changes to improve the structure and properties of metals. Including: 1 annealing. That is, the metal is heated to a temperature above the critical point to obtain a high temperature phase, and then slowly cooled, so that the metal undergoes a solid phase transformation under conditions close to equilibrium to improve the metal during solidification, normal deformation, welding or previous heat treatment. Tissue; it is also possible to heat the metal to a temperature at which no phase change occurs, allowing the metal to eliminate internal stress or to recover and recrystallize the metal undergoing cold deformation. Annealing is a heat treatment in which the internal structure of the metal approaches an equilibrium state. If the medium is cooled at a medium speed after obtaining a high temperature phase, the metal is made finer than the annealed structure to achieve an effect similar to annealing, and at the same time it plays a role of improving performance, which is called normalizing. 2 quenching. The metal is heated to a temperature above the critical point to obtain a high temperature phase, and then rapidly cooled to obtain an unbalanced structure to maintain a high temperature phase or form a metastable phase, thereby utilizing the good performance of the high temperature phase and preparing for the next heat treatment. For example, only the second phase is dissolved at a high temperature (the substrate does not undergo a phase change), and then quenched to retain the high temperature solid solution state to room temperature. It is called solution heat treatment. 3 tempered. The subsequent treatment of quenching heats the unbalanced structure after quenching to a temperature below the critical point, bringing the metal closer to the equilibrium structure; and controlling the progress of the phase transformation to obtain a suitable structure and properties of the metal. The process of dissolving the second phase at room temperature after solution treatment or by heating to a lower temperature is referred to as "aging treatment".
