Relationship between slow tensile strain rate and hydrogen embrittlement sensitivity of high strength aluminum alloy

Taking 7085 high strength aluminum alloy material as the research object, the hydrogen induced stress cracking of the material was studied by setting different slow tensile strain rates. At the same time, the fracture of the sample was observed by scanning electron microscope. The relationship between strain rate and hydrogen embrittlement sensitivity was preliminarily discussed, which provided reference for the establishment of hydrogen embrittlement sensitivity evaluation system of high strength aluminum alloy materials.
