초록
Hydrogen embrittlement refers to a phenomenon in which the ductility and toughness of steel materials are lowered by hydrogen absorbed in metal materials, especially steel, and the tendency to fracture without plastic deformation increases. Fracture due to hydrogen absorption is also called delayed fracture, and it mainly occurs at grain boundaries, stress concentration areas, or areas subject to tensile stress. From a practical point of view, hydrogen embrittlement is frequently associated with corrosion, welding, pickling, electroplating, etc., and in materials, it is prominently displayed in stainless steel or high tensile steel. Regarding the embrittlement mechanism, there is no generally accepted orthodoxy. In this study, A hydrogen embrittlement mechanism is proposed. In addition, the method of suppressing hydrogen embrittlement will be considered.
