What is the annealing time related to? Help you solve the problem of quenching-Kehua
In the annealing process, people will face many problems, such as what is the effect of the annealing time being too long? What is the annealing time related to? I believe that all of you are not very familiar with annealing, so follow us for details Annealing it under the understanding. Wire annealing time 1. Annealing Kehua pointed out that annealing is a metal heat treatment process, which means that the metal is slowly heated to a certain temperature, kept for a sufficient time, and then cooled at a suitable speed. The purpose is to reduce hardness, improve machinability; eliminate residual stress, stabilize size, reduce deformation and crack tendency; refine grains, adjust organization, and eliminate organizational defects. To be precise, annealing is a heat treatment process for materials, including metallic materials and non-metallic materials. Moreover, the purpose of annealing of new materials is similar to that of traditional metal annealing. 2. What is the annealing time? Kehua proposed that the annealing time is related to the length of the primer, generally 30s-1min. Therefore, if the annealing time is too long, the enzyme will work for a long time at low efficiency, and the enzyme will not be affected. The activity has a great influence. Even when the best extension temperature is 72 degrees, the best results may not be obtained. Therefore, the extension temperature is generally longer than the annealing temperature. This is why the enzyme can be activated and the enzyme can be activated. High-efficiency amplification efficiency can be maintained. Wire annealing time 3. What is the effect of excessive annealing time? The length of the annealing time affects the structural relaxation of the material, because the material rises to a certain temperature and the structural relaxation phenomenon occurs, that is The reorganization of the internal dislocation keys you mentioned takes a certain amount of time. The annealing temperature holding time is preferably longer than this relaxation time. In short, everyone needs to master the annealing time. If the time is too long, it will cause damage to the material and affect the final use. Of course, each material has different properties and needs to be analyzed in detail.
