Introduction Hydrogen embrittlement (HE) poses a serious risk to aluminum structural rods used in demanding applications such as aerospace frames, automotive hydrogen tanks, and civil infrastructures. When atomic hydrogen penetrates the metal, it can degrade ductility and fracture resistance, leading to sudden, unexpected failures. Engineers and
