摘要：
The influence of ageing temperature on hydrogen solubility in maraging steel N18K9M5T was investigated. Maximum solubility after ageing at 450 degree C is associated with the formation of hydrogen traps due to local microstresses during precipitation of coherent intermetallic particles in previous stages of ageing. The energy of hydrogen interaction with the particles is estimated as 0. 4 ev, which exceeds the energy of hydrogen interaction with dislocations and titanium atoms.
