چکیده انگلیسی
Effects of hydrogen on the fracture toughness of a X70 pipeline steel were investigated in the cases of hydrogen pre-charging and dynamic hydrogen charging in 0.5 mol/L H2SO4 solution under slow strain rate tensile testing. Under the hydrogen pre-charging, the fracture toughness decreased in a linear relationship with the hydrogen concentration as the hydrogen concentration was more than 1 ppm in weight. The fracture surfaces were characteristic of dimples. Under the dynamic hydrogen charging, the fracture toughness for hydrogen-induced cracking decreased linearly with logarithm of the hydrogen concentration without stress. The hydrogen-induced fracture had the appearance of cleavage facets.
