The results show that when charging current density i<20 mA/cm2, there are no hydrogen blisterings and microcracks on the surface of the specimens and the normalized threshold stress intensity factor is KIH/KIC=0.63. where KIC=62.2 MPa.m1/2. When i20 mA/cm2, hydrogen blisterings and microcracks appear in the specimen under no loading, while KIH}/ KIC decreases from 0.63 to 0.26. The critical pressure necessary for a stable blistering formation is pi3.6 GPa, and that for cleavage propagation of the blistering is pC3.9 GPa. The crack formed through blistering cracking will be arrested after propagating 20 to 30 um, and the arrested crack will propagate again because of entering of hydrogen atoms. At last, the blistering with cracking will be broken and leave local cleavage fracture surface with arrested lines on the surface of the sample without loading.
