... are commonly observed on specimens tested in hydrogen (Stalheim, 2010). For the fracture toughness test procedure, ASME B31.12 originally requests to apply ASTM E1681 which is the linear elastic fracture mechanics (LEFM) test, with either constant load or constant displacement condition. But it was pointed out...

... solution containing ammonium thiocyanate, which promotes hydrogen entry. For conventional cathodic charging, SSRT was performed after hydrogen was introduced into the specimen beforehand by electrochemical charging and then electroplated to prevent hydrogen release (Wang et al., 2005). Therefore, specimens...
