The influences of anisotropy of material on static and dynamic SCC crack growth rates including the case of part-through one have been investigated using high-strength aluminum alloy ZK 141 (JIS 7N01) sensitive to active path corrosion type SCC. As for through crack growth, the crack plane orientation had a great influence not only on the crack growth rate but also on the threshold value; when the crack growth direction was longitudinal, i.e., in S-L and T-L specimens, anodic dissolution at grain boundaries was easily brought about, resulting in an enhancement of crack growth rate and a decrease in threshold value with respect to L-T specimens, where the crack growth direction was long transverse. This crack growth enhancement and the decrease in threshold value were especially marked on S-L specimens. Moreover, superimposed vibratory stresses had a great influence on the crack growth rate for T-L and L-T specimens. However, the dynamic SCC crack growth rate was smaller than that of static SCC for S-L specimens, with a slightly higher KDSCC value than that of KISCC, which results from crack branching. In a corrosive environment, part-through static and dynamic SCC cracks grew in the longitudinal direction as well as in the surface and the depth directions. The longitudinal cracks grew under a mixed loading of Mode I and Mode II.
