铝板的两种强化方法

不同的行业和领域对铝板的性能要求也不同,在机械加工等行业,对铝板的硬度要求特别严格,这就要求在铝板生产过程中进行硬化处理,以提高铝板的硬度,达到性能要求。目前主流的加工方法有两种,分别是加工强化和固溶强化,下面分别对两种方法作简单先容:
Different industries and fields have different performance requirements for aluminum plate. In machining and other industries, the hardness requirements for aluminum plate are particularly strict, which requires hardening treatment in the production process of aluminum plate to improve the hardness of aluminum plate and meet the performance requirements. At present, there are two mainstream processing methods, namely processing strengthening and solid solution strengthening
加工强化铝板

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,且相互缠结并形成胞状结构,阻碍位错运动。
Work hardening, also known as cold work hardening, is the cold deformation of aluminum plate below the recrystallization temperature, such as forging, calendering, drawing, stretching, etc. during cold deformation, the dislocation density in aluminum plate increases, and entangles with each other to form cellular structure, which hinders the dislocation movement.


变形度越大位错缠结越严重,变形抗力越大,强度越高。冷变形后强化的程度随变形度、变形温度及材料本身的性质而不同。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。
The larger the deformation degree is, the more serious the dislocation entanglement is, the greater the deformation resistance is, and the higher the strength is. The degree of strengthening after cold deformation varies with the deformation degree, deformation temperature and the properties of the material 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.
固溶强化铝板

在纯铝中添加某些合金元素形成无限固溶体或有限固溶体,不仅能获得高的强度,而且还能获得优良的塑性与良好的压力加工性能。在一般铝板中固溶强化常用的合金元素是铜、镁、锰、锌、硅、镍等元素。
It can not only form good solid solution with limited pressure or high plasticity, but also obtain good solid solution properties. Copper, magnesium, manganese, zinc, silicon, nickel and other elements are commonly used in solution strengthening of general aluminum plate.
一般铝板的合金化都形成有限的固溶体,二元合金均形成有限固溶体,并且都有较大的极限溶解度能起较大的固溶强化效果。
In general, the alloying of aluminum plate forms limited solid solution, and the binary alloy forms limited solid solution, and all of them have higher limit solubility, which can play a greater solid solution strengthening effect.
经过强化的铝板,其硬度性能都会得到明显提升,但是其硬度无法一直提升下去;当达到硬度上限的时候,无论何种方法,都无法继续提高铝板的硬度,只能选择基础硬度就更高的牌号。
After strengthening, the hardness performance of aluminum plate will be significantly improved, but its hardness can not be improved all the time; when it reaches the upper limit of hardness, no matter what method, it can not continue to improve the hardness of aluminum plate, only choose the brand with higher basic hardness.
