1、 The essence of dissolution precipitation mechanism introduced by aluminum plate manufacturer
In the process of aluminum plate production, the essence of dissolution precipitation mechanism is that the atoms of one phase crystal transfer to another phase crystal rapidly. In order to complete the transfer of atoms from one phase to another, in addition to ensuring that the two phases have greater mutual solubility, there must be some conditions.
2、 In order to achieve the essence of the dissolution precipitation mechanism, we need to pay attention to the conditions
① Because the migration of atoms may be carried out from the surface layer of the phase, it should be accompanied by a large solubility change with the change of temperature or the change of the surface size and curvature of the original phase crystal.
② During deformation, it must be beneficial to the diffusion process of high-speed dissolution and deposition. That is to say, the temperature should be high enough.
溶解-沉淀机理的重要特点是塑性变形在两相间的界面上进行，又由于金属的沉淀很容易在显微空洞和显微裂纹中进行，则原子的相间转移可使这些显微空洞和裂纹消 除，起着修 复损伤作用，从而可使金属塑性显著增 大。
The important characteristic of the dissolution precipitation mechanism is that the plastic deformation takes place at the interface between the two phases, and because the metal precipitation is easy to take place in the micro cavities and micro cracks, the inter phase transfer of atoms can eliminate these micro cavities and cracks, play a role in repairing the damage, and thus significantly increase the metal plasticity.
