摘 要: 提出了確定鋁合金固溶保溫時(shí)間的相關(guān)強(qiáng)化技術(shù)。 該技術(shù)充分考慮了影響鋁合金性能的諸因素以及這些因素之間的相互影響和相互補(bǔ)償關(guān)系， 克服了傳統(tǒng)的由單一厚度因素確定固溶保溫時(shí)間的局限性。 實(shí)踐證明： 與目前最先進(jìn)的美國軍用標(biāo)準(zhǔn)MILH6088G相比， 用該相關(guān)強(qiáng)化技術(shù)確定固溶保溫時(shí)間可使產(chǎn)品力學(xué)性能提高10%～40%， 大幅度地提高塑性指標(biāo)， 減小各向異性， 更有效地控制粗晶和粗晶環(huán)。

Abstract:A multiple-factor related strengthening technology on aluminum alloy solution treating is put forward. It has fully considered various factors which influence the properties of aluminum alloy, as well as the interaction and inter-compensation among them. It eliminates the one-sidedness of the traditional method which determines the holding time of solution only by the thickness. Compared to the American Military Standard MIL-H-6088G which is considered as the most advanced one by now, the multiple-factor related strengthening technology can improve the mechanical properties of aluminum alloy products by 10 to 40 percent, improve the plastic index obviously, reduce the anisotropy, and controll the coarse grain and the coarse grain annulus effectively.
Key words: solution treating solution holding time related strengthening aluminum alloy
