AZ91 consists of an -matrix with extensive -particles, whereas AZ31 and AM30 consist only of an -matrix with an Al-concentration similar to that in AZ91. The presence of -particles in AZ91 was associated with: (i) a lower threshold stress, σSCC, for AZ91 (55–75MPa) relative to AZ31 (105–170MPa) and AM30 (130–140MPa); and (ii) a different SCC initiation mechanism for AZ91 relative to AZ31 and AM30. The SCC velocity, Vc, for AM30 (3.6×10−10 to 9.3×10−10 m/s) was lower than that for AZ91 (1.6×10−9 to 1.2×10−8 m/s) and AZ31 (1.2×10−9 to 6.7×10−9 m/s). This was attributed to the influence of Zn and second phase particles, which are more concentrated in AZ31, on the diffusivity of H in the -matrix.}, note = {Online available at: \url{https://doi.org/10.1016/j.msea.2007.11.064} (DOI).
