Abstract:

The combination of atomization and smelting fabricated high strength Al-6Zn-2Mg-2Cu alloy. Microstructure was observed and analyzed by optical microscopy and SEM. The alloy featured with refined grains and even distribution. After being solution treated at 475°C for 1.5h, following multi-pass rolling with total reduction of 33% and aging at 120°C for 40h, the yield strength was 592MPa, peak stress of 597MPa and elongation of 12.2%.
