Abstract
A new thermal desorption spectroscopy apparatus was used to study hydrogen in four martensitic advanced high-strength steels (designated MS980, MS1180, MS1300 and MS1500) after gaseous hydrogen charging, and after hydrogen charging electrochemically in 0.1Â M NaOH and in 3.5Â wt.% NaCl. The hydrogen concentration did not correlate strongly with steel strength. For MS1500, a relationship was derived between equivalent hydrogen fugacity and the applied charging overpotential. Also for MS1500, the trap binding energies were evaluated to be 26.4Â kJÂ molâ1 and 61.0Â kJÂ molâ1, which were interpreted as dislocation and interface hydrogen traps.
