文摘

•: Nb₃₀(Ti, Hf)₃₅Co₃₅ alloys of fully lamellar eutectic structure were fabricated.
•: Aligned eutectic structure was generated by directional solidification (DS).
•: As-cast Nb₃₀(Ti, Hf)₃₅Co₃₅ were subject to hydrogen embrittlement during permeation.
•: DS Nb₃₀Ti₂₅Hf₁₀Co₃₅ exhibits higher permeability than its as-cast counterpart.
•: DS Nb₃₀Ti₂₅Hf₁₀Co₃₅ exhibits excellent resistance against hydrogen embrittlement.
