A NEW APPROACH TOWARDS THE EARLY RECOGNIT ION OF H-INDUCED STRESS-CORROSION CRACKING

The investigations show that diffusion of hydrogen into ferritic stede l leads to changes in the micromagnetic measured values. This can be e xplained by the interaction of the magnetic structure with locally occ urring fields of residual stress. In principle, an early recognition o f H-induced stress corrosion cracking is thus possible.
