TiC and Cu precipitates were found to provide H trapping sites, however, dislocations without C were not observed to trap H. The order of trapping from highest to lowest concentrations of deuterium (D) is as follows: TiC decorated dislocations > high energy grain boundaries > low energy grain boundaries.HIGH-STRENGTH; PARTICLES; SITESHydrogen trapping at dislocations, carbides, copper precipitates and grain boundaries in a dual precipitating low-carbon martensitic steeljournal article10.1016/j.scriptamat.2022.1149342-s2.0-85135399042WOS:000886069500007https://api.elsevier.com/content/abstract/scopus_id/85135399042
