SUPER-HIGH STRENGTH NON-RAPIDLY SOLIDIFIED ALUMINUM ALLOY AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2017/215104
Kind Code:
A1
Abstract:
Provided is a 770 Mpa-level super-high strength non-rapidly solidified aluminum alloy, wherein same comprises zinc at 8.8-9.4 wt%, magnesium at 2.75-2.85 wt%, copper at 1.8-2.2 wt%, zirconium at 0.25-0.55 wt%, strontium at 0-0.025 wt%, and the balance is aluminum; and the ratio of the mass percent of Zn and that of Mg in the alloy elements should satisfy 3 ≤ WtZn/WtMg ≤ 4, and the mass percent of Mg, i.e. WtMg, should satisfy 2% ≤ WtMg ≤ 3%. The alloy is prepared and obtained by means of fusion casting-homogenizing annealing-hot extrusion-solid solution treatment-aging treatment.
