It has been well documented that solute hydrogen atoms increase the mobility of dislocations in metals and alloys, thus promoting highly localized deformation which eventually leads to the rupture of a material. However, little is known about the mechanism of hydrogen-enhanced dislocation mobility that influences the macroscopic fracture process. In this paper, the high resolution X-ray tomography is used to clarify the influence of hydrogen on the initiation and propagation of quasi cleavage fracture in Al-Zn-Mg-Cu alloys. The initiation and propagation of the quasi cleavage crack are discussed by measuring 3D strain distribution ahead of a crack tip in terms of hydrogen embrittlement models.
