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 tensile properties of the as-deposited Ni3Fe alloy at different hydrogen pressures and at different current densities were studied. The results show that with the increase of hydrogen pressure or current density, the elongation of the alloy first decreases rapidly and then gradually becomes constant. The hydrogen embrittlement factor of the alloy shows the same dependence on the hydrogen pressure or current density. The embrittlement mechanism of the ordered Ni3Fe alloy in hydrogen is caused by the hydrogen atoms generated by the catalytic reaction entering into the alloy, and the degree of embrittlement of the alloy is related to the quantity of hydrogen atoms entering the alloy.
