Abstract:The hydriding behavior of the VT5-1 alloy (92.05 wt % Ti + 4.52 wt % Al + 3.43 wt % Sn) in the form of spherical particles 0.1, 0.4, 0.6, and 0.8 mm in diameter was studied at temperatures from 820 to 973 K and hydrogen pressures from 1 to 6 MPa. The results indicate that the absorption capacity of VT5-1 is lower than that of titanium and that the thermal stability of the resultant mixed-metal hydride is lower than that of titanium dihydride.
