Aluminium sheet 5052 alloy processing strengthening, also known as cold work hardening, refers to the cold deformation processing of metal materials below the recrystallization temperature, such as forging, calendering, drawing, stretching, etc. during cold deformation, the dislocation density in the metal increases, entangles with each other and forms a cellular structure, hindering the dislocation movement. The greater the deformation, the more serious the dislocation entanglement, the greater the deformation resistance and the higher the strength. The level of strengthening after cold deformation varies with the degree of deformation, deformation temperature and the properties of the data itself. When the same material is cold deformed at the same temperature, the greater the deformation, the higher the strength and the lower the plasticity.
Adding some alloy elements to pure aluminum to form infinite solid solution or finite solid solution can not only obtain high strength, but also obtain excellent plasticity and good pressure workability. In common aluminum alloys, the most commonly used alloying elements for solid solution strengthening are copper, magnesium, manganese, zinc, silicon, nickel and so on. The alloying of ordinary aluminum constitutes a limited solid solution, such as Al Cu, Al Mg, Al Zn, Al Si, Al Mn and other binary alloys constitute a limited solid solution, and all have a large limit solubility, which can play a large solid solution strengthening effect.
