一、對合金鋁板材進(jìn)行固溶處理:將其從金屬材料中分離出來(lái)的熔融到固體中。經(jīng)固化后的鋁合金板材具有較低的稀釋度和較好的塑性。固溶工藝的目標是得到一個(gè)用于組織陳化的過(guò)飽和固溶物。
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.
鋁板生產(chǎn)廠(chǎng)家時(shí)效處理又稱(chēng)為脫溶分解,即時(shí)效解溶,固溶體從高溫迅速降溫至固體溶解度曲線(xiàn)之下,因快速冷卻,未及時(shí)析出,而產(chǎn)生過(guò)飽和固溶體,隨后,在低溫條件下,此非穩定過(guò)飽和固溶體隨時(shí)間而出現脫溶分觸,隨時(shí)效溫度和固溶體組成的差異,在時(shí)效脫溶期間,會(huì )出現亞穩定的亞穩定沉淀相,這些沉淀相與母相共格或局部共格,從而增強了合金鋁板的強度。
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.
時(shí)效解溶是一種對金屬進(jìn)行增強的工藝,因此又稱(chēng)為時(shí)效處理或沉淀處理??梢苑殖蓛深?lèi):天然時(shí)效和人為時(shí)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、自然時(shí)效是在室外放置超過(guò)六個(gè)月,它就會(huì )慢慢成形,這樣就可以消除或減小剩余應力。
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、鋁板生產(chǎn)廠(chǎng)家人工時(shí)效是將鑄件在550~650℃下進(jìn)行熱處理,其過(guò)程中的剩余應力要完全消除,而不需要人工時(shí)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、合金鋁板材的固溶時(shí)效:采用固溶、陳化兩種方法。鋁板生產(chǎn)廠(chǎng)家通過(guò)對合金鋁板進(jìn)行固溶處理,使其在常溫下或略高于常溫下進(jìn)行脫溶、降解,使其硬度、強度提高,以實(shí)現增強。
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.
