EFFECT OF Ti AND V ON HYDROGEN-DISLOCATION INTERACTION IN Fe
Ti和V对Fe中氢与位错交互作用的影响

The hydrogen induced cold work peaks (H-CWP) related to hydrogen-dislocation interaction for Fe-0.5 wt-% Ti and Fe-0.5 wt-% V alloys have beeninvestigated and the activation energies for the peaks obtained. The binding energiesbetween hydrogen and dislocation have also been estimated. Significant differenceon H-CWP for two alloys has been observed, that implies the effect of elements onH-CWP of Fe is significant. The stronger the interaction between hydrogen andalloy element is, the more significant the effect is. It is noticed that there issome correlation between the results of internal friction ditermination and themechanical properties.
