一、对合金铝板材进行固溶处理:将其从金属材料中分离出来的熔融到固体中。经固化后的铝合金板材具有较低的稀释度和较好的塑性。固溶工艺的目标是得到一个用于组织陈化的过饱和固溶物。

First, the alloy aluminum plate solution treatment: it is separated from the metal material melting into a solid. The cured aluminum alloy sheet has lower dilution and better plasticity. The goal of solution process is to obtain a supersaturated solution for tissue aging.
铝板生产厂家时效处理又称为脱溶分解,即时效解溶,固溶体从高温迅速降温至固体溶解度曲线之下,因快速冷却,未及时析出,而产生过饱和固溶体,随后,在低温条件下,此非稳定过饱和固溶体随时间而出现脱溶分触,随时效温度和固溶体组成的差异,在时效脱溶期间,会出现亚稳定的亚稳定沉淀相,这些沉淀相与母相共格或局部共格,从而增强了合金铝板的强度。

Aluminum manufacturers aging treatment, also known as desolventizing decomposition, namely XieRong limitation of solid solution from under high temperature and rapid cooling to solid solubility curve, due to the rapid cooling, failed to timely precipitation, supersaturated solid solution, then, under the condition of low temperature, the unstable supersaturated solid solution with time and appear desolventizing points touch, as of solid solution and aging temperature difference, During the aging period, metastable metastable precipitates appear, which are common or locally common with the parent phase, thus enhancing the strength of the alloy aluminum plate.

时效解溶是一种对金属进行增强的工艺,因此又称为时效处理或沉淀处理。可以分成两类:天然时效和人为时效:

Aging dissolution is a kind of metal strengthening process, so it is also called aging treatment or precipitation treatment. It can be divided into two categories: natural aging and artificial aging:
1、自然时效是在室外放置超过六个月,它就会慢慢成形,这样就可以消除或减小剩余应力。

1, natural aging is placed outdoors for more than six months, it will slowly take shape, so that you can eliminate or reduce the residual stress.

2、铝板生产厂家人工时效是将铸件在550~650℃下进行热处理,其过程中的剩余应力要完全消除,而不需要人工时效。

2, aluminum plate manufacturers artificial aging is to heat the casting at 550~650℃, the residual stress in the process to be completely eliminated, without the need for artificial aging.

二、合金铝板材的固溶时效:采用固溶、陈化两种方法。铝板生产厂家通过对合金铝板进行固溶处理,使其在常温下或略高于常温下进行脱溶、降解,使其硬度、强度提高,以实现增强。

Ii. Solution aging of alloy aluminum plate: two methods of solution and aging are adopted. Aluminum plate manufacturers through solid solution treatment of alloy aluminum plate, so that it is dissolubilized and degraded at room temperature or slightly higher than room temperature, so that its hardness and strength improve, in order to achieve strengthening.
