研究了超高强铝合金的固溶处理和不同时效工艺。结果表明，ＤＳＡ处理可明显改善超高强铝合金的强度和抗腐蚀综合性能。同时讨论了ＤＳＡ处理改善合金强度和抗蚀性能的机理。
The solution treatment and aging process of ultra high strength aluminum alloy were studied. The results show that DSA treatment can significantly improve the strength and corrosion resistance of ultra-high strength aluminum alloy. The mechanism of DSA treatment to improve the strength and corrosion resistance of the alloy was also discussed.
