In the practice, fine-grained structural steels appear to be more or less susceptible to hydrogen induced cracking, probably because of various strong interactions between the absorbed hydrogen and to various alloying elements or inclusions, acting as traps. Such effect examined by cathodic polarization, and by SEM examination of the fracture surfaceTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaInštitut za kovinske materiale in tehnologije
