Hydrogen absorption in as-cast bcc single-phase Ti–Al–Nb alloys
چکیده انگلیسی

In this article, hydrogen absorption properties of bcc single-phased as-cast Ti–Al–Nb alloys near pseudo-binary section at about 50 at.% of Ti are considered. Possible reasons of enhancing hydrogen capacity with the increasing of Nb content from ∼34 to ∼42 at.% and decreasing Al content from ∼13 to ∼6 at.% are discussed. The alloys and corresponding hydrides have been characterized by X-ray diffraction. Ti–6 at.% Al–42 at.% Nb is found to absorb maximum hydrogen H/M = 1.88 (∼2.81 wt.%) to form a hydride at 500 °C temperature and 1.2 MPa. Beneficial effect of mild cold rolling deformation on hydrogen capacity is noted. All the studied compositions demonstrate good kinetics and absorb hydrogen quickly, within 20–30 min after activation.
