摘要：

The effect of hydrogen on the plasticity and fracture mode of pure iron and iron containing iron oxides, aluminum oxide and cementite particles has been studied. Cathodic hydrogen charging causes the embrittlement of Fe, Fe-Al2O3 and Fe-C alloys and little or no degradation effect on Fe-FeO and Fe-FeO-Al2O3 materials, despite the high strength of those alloys and high amount of absorbed hydrogen. High hydrogen resistivity of alloys containing iron oxides accounts for the weak iron oxide/iron matrix cohesion established by the internal friction measurements. The effect of hydrogen softening and hydrogen enhanced local plasticity in the resistance of studied alloys to the hydrogen action has been discussed.
