Abstract

The effect of alloy stoichiometry and boron doping on the H₂-induced environmental embrittlement of Ni₃Fe intermetallic alloys was investigated at room temperature. The results show that the alloy stoichiometry of Ni₃Fe does not affect the sensitivity to hydrogen embrittlement and that the H₂-induced environmental embrittlement is also not related to the surface elemental segregation induced by long time ordering. The results also indicate that the boron doping can effectively suppress the H₂-induced embrittlement of ordered Ni₃Fe intermetallics. The beneficial effect of boron is believed to be due to its strong segregation to grain boundaries and the enhancement of the boundary cohesive strength of Ni₃Fe alloys. © 2008 Elsevier Ltd.
