研究了有序态Ni3Fe合金在不同氢气压力中和在不同电流密度电解渗氢时合金的拉伸性能.结果表明:随着氢气压力或电流密度的增加,合金的延伸率先快速下降,随后逐渐趋于恒定:合金的氢脆因子与氢气压力或电流密度之间呈相同的依赖关系.有序态Ni3Fe合金在氢气中的脆化机制是催化反应生成的氢原子进入合金所致,合金的脆化程度与进入合金的氢原子数量有关.

The mechanical properties of ordered Ni3Fe alloy in gaseous hydrogen or simultaneously at hydrogen charging were investigated.The results show that the ductility of the ordered Ni3Fe alloys are fast decreasing,then turns to be stable with the increase of hydrogen pressure and current density during simultaneous hydrogen charging.The hydrogen embrittlement factor has the same dependence on the hydrogen pressure and charging current density.The mechanism of hydrogen embrittlement of ordered Ni3Fe alloy in gaseous hydrogen is the atomic hydrogen diffusing into alloy through the catalytic reaction,and the degree of embrittlement is proportional to the amount of hydrogen atoms diffusing into the alloy.
