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 0.1 M NaOH and in 3.5 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 26.4 kJ mol −1 and 61.0 kJ mol −1 , which were interpreted as dislocation and interface hydrogen traps.

一些马氏体高级高强钢电化学充电过程中的等效氢逸度

摘要 使用一种新的热解吸光谱仪研究了四种马氏体高级高强度钢（命名为 MS980、MS1180、MS1300 和 MS1500）在气态充氢后以及在 0.1 M NaOH 和 3.5 wt.% 中电化学充氢后的氢氯化钠。氢浓度与钢强度没有很强的相关性。对于 MS1500，推导出等效氢逸度与施加的充电过电位之间的关系。同样对于 MS1500，陷阱结合能被评估为 26.4 kJ mol -1 和 61.0 kJ mol -1 ，这被解释为位错和界面氢陷阱。
