文摘

•: Microstructures and hydrogen permeability of Nb–HfCo alloys have been investigated.
•: Pronounced high hydrogen permeability is found in Nb–HfCo alloys.
•: Nb₄₀Hf₃₀Co₃₀ alloy shows the highest permeability of 4.96 × 10⁻⁸ mol H₂ m⁻¹ s⁻¹ Pa^−0.5.
•: The eutectic microstructure in Nb–HfCo alloys contributes much to hydrogen permeation.
