It is known that the susceptibility to stress corrosion cracking of Al-Mg alloy increase with increasing Mg content, whereas the strength of Al-10Mg alloy reach to that of 2000 and 7000 series Al alloys. In-situ observation of the stress corrosion cracking of a hydrogen charged Al-10Mg alloy was conducted by using synchrotron X-ray mi-crotomography in SPring-8. The corrosion area and crack were observed in hydrogen charged material with water atmosphere. The corrosion and crack grow up with increasing applied strain. In addition, deformation localization and high hydrostatic strain that was caused by nucleation of nanovoids during deformation was also observed in crack tip. These observations indicated that the stress corrosion cracking of an Al-10Mg alloy occurs due to the influence of hydrogen.
