This program was initiated on 1 January 1978. During 1979, the effect of copper content on the FCP behavior of four Al-6Zn-2Mg-XCu-T7351 alloys was investigated in dry air and distilled water and compared with last years study of the T651 condition. The peak-aged-treatment exhibited a lower growth rate in dry air over the range of delta K studied, and also displayed a higher threshold and resistance to fatigue cracking near the threshold in the distilled water environment.
