| 中文摘要 | The hydrogen permeation behavior in a Fe3Al-based alloy, with three types of heat treatments, was investigated by an ultrahigh vacuum gaseous permeation technique at the temperature range of 240-320degreesC. A well-defined second stage is observed in hydrogen permeation curves of the Fe3Al alloy superimposed on the basic curves. On the basis of optical microstructures, determined permeabilities and diffusivities, corresponding activation energies, it is suggested that the two sigmoidal curves result from the ordered B-2 phase and disordered alpha-Fe phase in the Fe3Al alloy; the first stage of permeation reflects the hydrogen transport in matrix disordered alpha-Fe phase, while the second stage reflects the hydrogen transport in ordered B-2 phase.
