| 摘要 |
The invention resides in the fabrication of a structural element comprising a laminated composite having one portion or layer comprising alpha-phase titanium aluminide and another adjacent portion or layer comprising gamma-phase titanium aluminide. Preferably, the gamma-phase portion or layer is joined with the alpha-phase portion or layer by such processes as hot-spraying, diffusion bonding, or vapor deposition. The invention contemplates the utilization of the structural element in the fabrication of the wall of a container or tank for storage of the hydrogen fuel material, where the gamma-phase titanium aluminide portion or layer is oriented so as to be placed in direct contact with the hydrogen fuel material, or at the least be oriented toward any hydrogen leak path.
