The Nb—Ti—Co alloy is preferably subjected to heat treatment at 800° C. or more so that the eutectic structure in the casted state can be changed to a granular structure. The Nb—Ti—Co alloy used there is preferably NbxTi(100-x-y)Coy, (x?70, 20?y?50 (mol %)). By properly predetermining the heating temperature and time, the resulting alloy exhibits improved hydrogen permeability in combination with a good hydrogen embrittlement resistance characteristic in the CoTi phase, making it possible to provide a practical hydrogen permeable membrane having an advantageously high performance.

  • Patent number: 7390348
    Abstract: In a multiphase hydrogen permeation alloy comprising a phase in charge of hydrogen permeation and a phase in charge of hydrogen embrittlement resistance, a structure in which the phase in charge of hydrogen permeability is continuously interconnected and in which more preferably the growth direction of the aforementioned phase in charge of hydrogen permeation lies aligned in the thickness direction of the permeation membrane. As the hydrogen permeation alloy, an Nb—Ti—Co alloy is exemplified, wherein the phase in charge of hydrogen permeability is made of an (Nb, Ti) phase and the aforementioned phase in charge of hydrogen embrittlement resistance is made of a CoTi phase. By virtue of the fact that the growth direction of the phase in charge of hydrogen permeation lies aligned in the thickness direction of the permeation membrane, the hydrogen permeation pass length becomes short to give further improved hydrogen permeation property.
