For hydrogen-assisted cracking of 2.25 Cr-1 Mo steel, the evaluation of the threshold stress intensity factor for subcritical crack growth was examined by employing the slow strain rate test. Also, by the method of recrystallization, a high strain region formed at the crack tip was observed, and the effect of hydrogen on plastic deformation was studied. By this experiment, it was shown that hydrogen promoted subcritical crack growth at a low stress intensity level, KIH(40∼80 MPa·m1/2)well below KIc(300∼400 MP·m1/2, and hydrogen also enhanced plastic deformation at the crack tip. This result suggests that the plastic deformation which is enhanced by hydrogen exerts large effects on subcritical crack growth in hydrogen-assisted cracking of 2.25 Cr-1 Mo steel.
