Ferrite / carbide interfaces in steels are known to be possible trapping sites for hydrogen atoms. The present work deals with hydrogen adsorption at ferrite / cementite interfaces in carbon steels. Experiments on hydrogenation of 1.0 pct C steel specimens having coarse and thin-plate lamellar pearlite structure (interlamellar spacing S ~ 0,36 and 0,085 mm) were carried out in H2S-containing solution according to NACE Standard TM 0177-2005. After hydrogenation the specimens were held in air for 4 months, and then hydrogen concentration was evaluated using LECO RH402 hydrogen analyzer. It was found to increase from 6.85 to 8.4 and from 8.45 to 13.5 wt. ppm (related to specimens not subjected to hydrogenising treatment) for the coarse and thi...
