Relationship between hydrogen embrittlement and second-phase particles in a 7075 aluminum alloy

With respect to hydrogen embrittlement process in a 7075 alloy in humid air, it has been claimed that cracks at second-phase particles result in intergranular cracking. In this study, slow strain rate tensile tests in two environments and microscopic surface observation were carried out to investiga...
