title = "Effect of ammonia impurity on hydrogen embrittlement of scm440 low-alloy steel in hydrogen gas",
abstract = "Ammonia (NH3) was added to hydrogen gas as an impurity, then hydrogen embrittlement (HE) of the SCM440 low-alloy steel was investigated by fracture toughness tests. NH3 showed inhibition of the HE when the loading rate was relatively high. However, the inhibitory effect decreased with the decrease in the loading rate, as well as with an increase in the gas pressure. It was found that NH3 acted as both an inhibitor of the HE and a cause of the HE depending on the loading rate and gas pressure.",
