The mechanism of stress-corrosion cracking in 7079 aluminum alloy was investigated by analysis of microstructural changes that occur during exposure to 3.5 per cent NaCl solution. During the corrosion reaction dislocation networks were generated within the grains and along strain-contour bands. Grain-boundary voids occurred where several of these bands originated or terminated. This suggests that the intragranular structure develops as a result of hydrogen entering the alloy and that the voids are propagated under applied load to form grain-boundary cracks. This study is in the preliminary stages and is being continued. (Author).

The report summarizes information from selected European papers and lectures that were published or presented between mid 1967 and July 1, 1968. Subjects discussed include: the nature of stress-corrosion, stress-corrosion in AlMg, AlMgZn, and AlMgSi alloys and testing for susceptibility to stress-corrosion cracking. (Author).

Wrought, high-strength aluminum alloys characteristically have markedly inferior resistance to stress corrosion in the short-transverse direction relative to resistance in the longitudinal and long-transverse directions. The anisotropy of resistance has been shown to be due to marked anisotropy of microstructure. Investigation of experimental and commercial 1 in. plate showed that the elongated, plate-like grain structure usually found in commercial materials was associated with short life while equiaxed or irregular grain structure was associated with significantly longer life. Excess alloy content resulting in second-phase particles in the microstructure contributes to the development of the undesirable elongated grain structure. Exposure at 650F under stress for times of 1400 or 2000 hr gave no indication that the steels PH 13-8 Mo and PH 14-8 Mo are susceptible to hot salt stress corrosion. Experiments to determine the kinetics of hot salt stress-corrosion cracking of Ti-8Al-1Mo-1V alloys are described. Cracking was observed at 500F, 50F lower than the lower temperature limit reported in prior investigations.

Program objectives were: (1) to study the effect of microstructure on susceptibility to stress corrosion cracking in the short-transverse direction of 7075-T6 aluminum alloy; and (2) to study the kinetics of stress-corrosion cracking at elevated temperature of candidate materials for structural applications in the trisonic transport in the presence of sea salt. It was hypothesized that the poor resistance to stress corrosion of high-strength, wrought aluminum alloys was due to the layered-type microstructure characteristic of these materials. Short life was associated with the layered-type of grain structure characteristic of commercial material, and long life was associated with irregular or equiaxed grain structures. The experimental results gave good support to the hypothesis.
