Abstract

Nb₃₀Ti₃₅Co₃₅ eutectic composites with various structure patterns were produced by directional solidification (DS), rolling and annealing. The relationship between structure and hydrogen permeability is investigated and discussed on the basis of the mixing rule. The measured hydrogen permeability of the parallel-type structure with the two eutectic phases aligned in parallel to the hydrogen permeation direction (generated by DS) is significantly higher than those measured for the other structure types. In contrast, a series-type structure with the two phases aligned perpendicular to the hydrogen permeation direction (generated by rolling) induces the lowest permeability. The variation of hydrogen permeability with different structure patterns is quantitatively explained by the mixing rule.
