    摘要:

    本文采用阴极充氢和真空拉伸方法研究了硼含量对氢原子在有序态Ni3Fe合金中扩散的影响。研究结果表明,当合金中硼含量CB≤0.06 wt.%时,氢原子在有序态Ni3Fe合金中的扩散系数随CB的增加而逐渐降低,而扩散激活能逐渐增大。当CB > 0.06 wt.%后,氢原子的扩散系数随CB的增加而变化很小,而扩散激活能略有减小。原子探针层析方法证实了硼原子在有序态Ni3Fe合金中晶界处发生偏聚。对比研究硼含量对有序态Ni3Fe合金中氢扩散系数及对合金在氢气环境中氢脆因子的作用,确认硼原子降低有序态Ni3Fe合金在氢气环境中的氢脆敏感性的机理是硼原子降低了氢原子在合金中的沿晶扩散系数。

    Abstract:

    In this work, the effect of boron content (CB) on the diffusion of hydrogen has been investigated in the ordered Ni3Fe alloy by using the methods of the cathodic charging hydrogen and vacuum stretching. It can be found that the diffusion coefficient of hydrogen decreases while the diffusion activation energy increases with the increase of boron content when CB≤0.06 wt%. The diffusion coefficient of hydrogen is subject to negligible changes and the diffusion activation energy decreases slightly when CB > 0.06 wt %. The atom probe chromatography reveals the segregation of boron atoms at grain boundaries in ordered Ni3Fe alloys. Through the comparative study of the effect of boron content on hydrogen diffusion coefficient and hydrogen embrittlement factor, it is confirmed that boron atom could reduce the hydrogen embrittlement sensitivity of ordered Ni3Fe alloy in hydrogen environment with the reason of reducing the intergranular diffusion coefficient of hydrogen by boron atom in the alloy.
