抄録

Stress corrosion cracking (SCC) behavior of Al-10Mg aluminium alloys is studied with the help of the high resolution X-ray tomography in the present research. The SCC-induced crack is formed from the corrosion pit near the surface, and gradually propagates and coalescence with the voids due to the fracture of β phase ahead of the crack tip at low applied strain levels. In addition, hydrogen concentration in the ligament between the SCC-induced crack tip and voids accelerates the propagation of the crack, indicating that hydrogen concentration and partitioning among various trap sites dominates the SCC and entire fracture of Al-10Mg aluminium alloys.
