Abstract
A (Nb, Ti) phase in an Nb—Ti—Co alloy is composed of a granular structure. 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 NbTiCo, (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.
