Figure 28. The effect of the irradiation and the cathodic current density on the delayed fracture of 15Kh3MFA steel: current density 0.6 A / dm 2 (o, ) or 5.0 A / dm 2 ( ), the specimens are either unirradiated (o, ) or irradiated( ) (Alekseenko et al., 1977).

Figure 29. The reduction of area at fracture at the notch in the delayed fracture tests at different stress levels: unirradiated specimens (o, ), at temperature 100 - 150°C irradiated specimens ( ) , current density 0.6 A / dm 2 ) and 300-350°C irradiated specimens ( ) (Alekseenko et al. 1977).

Irradiation temperature was seen by Alekseenko et al. (1977) to affect the diffusion of hydrogen in steel so that irradiation at 300-350°C has an effect of one order of magnitude and at 100-150°C has an effect of more than two orders of magnitude. The
