Vk. Saxena et al., ELECTRON-BEAM IRRADIATION EFFECTS ON FATIGUE-CRACK GROWTH RESISTANCE IN AN AUSTENITIC STEEL, International journal of fatigue, 16(7), 1994, pp. 479-484
The effect of electron beam surface treatment (EBST) on fatigue crack
growth (FCG) resistance of an austenitic steel has been investigated.
The EBST results in significant improvement in the FCG resistance. The
beneficial effect is attributed to extensive crack closure as a resul
t of residual stresses originating during EBST. A comparison with the
FCG data of the alloy surface treated with other high-energy beam sour
ces such as lasers reveals that EBST could provide similar improvement
s in the FCG resistance.
