1.加工强化铝板
1. Processing strengthened aluminium sheet
加工强化也称冷作硬化，就是铝板在再结晶温度以下冷变形加工如锻造、压延、拉拔、拉伸等，冷变形时，铝板内部位错密度增大，且互相缠结并构成胞状结构，阻止位错运动。变形度越大位错缠结越严峻，变形抗力越大，强度越高。冷变形后强化的水平随变形度、变形温度及材料本身的性质而不一样。同一材料在同一温度下冷变形时，变形度越大则强度越高，塑性则越低。
Processing hardening is also called cold work hardening, which means that the aluminum sheet is cold deformed below the recrystallization temperature, such as forging, calendering, drawing, drawing, etc. During cold deformation, the dislocation density inside the aluminum sheet increases, and intertwines with each other to form a cellular structure to prevent dislocation movement.  The larger the deformation degree, the more severe the dislocation entanglement, the greater the deformation resistance and the higher the strength. The level of hardening after cold deformation varies with the degree of deformation, the temperature of deformation and the nature of the material itself. When the same material is cold deformed at the same temperature, the greater the deformation degree, the higher the strength and the lower the plasticity.
2.固溶强化铝板
2. Solution strengthened aluminium sheet
在纯铝中添加某些合金元素构成无限固溶体或有限固溶体，不只能获得高的强度，而且还能获得优秀的塑性与出色的压力加工功用。在通常铝板中固溶强化较常用的合金元素是铜、镁、锰、锌、硅、镍等元素。通常铝板的合金化都构成有限的固溶体，如Al-Cu，Al-Mg，Al-Zn，Al-Si，Al-Mn等二元合金均构成有限固溶体，而且都有较大的极限溶解度能起较大的固溶强化作用。
Adding some alloying elements to pure aluminium to form infinite solid solution or finite solid solution can not only obtain high strength, but also obtain excellent plasticity and excellent pressure processing function. The most commonly used alloying elements in solution strengthening of aluminium sheets are copper, magnesium, manganese, zinc, silicon and nickel. Usually, the alloying of aluminium sheets constitutes a limited solid solution, such as Al-Cu, Al-Mg, Al-Zn, Al-Si, Al-Mn binary alloys, which constitute a limited solid solution, and all have a larger limit solubility which can play a larger role in solid solution strengthening.

                                     
经过强化的铝板，其硬度功用都会得到显着进步，可是其硬度无法一向进步下去；当抵达硬度上限的时分，不论何种方法，都无法持续进步铝板的硬度，只能选择根底硬度就更高的商标。
After strengthening, the hardness function of aluminium sheet will be improved remarkably, but its hardness can not always improve; when the upper limit of hardness is reached, no matter what method, the hardness of aluminium sheet can not be improved continuously, only the trademark with higher hardness at the bottom can be chosen.
