| Abstract: | Abstract: The effect of the desaturation aging (DSA) treatment on the strength and the corrosion resistance of ultra high strength aluminium alloys were studied. The results showed that the ideal strength of ultra high strength aluminium alloys can be obtained by DSA treatment (about 10% greater yield strength than 7150T77 alloy), and the stress corrosion resistance relates to the peak strength T6 type tempers was obvious improved. The principle of improving the strength and corrosion resistance of the alloy by DSA treatment was discussed. |
