Abstract

The effects of hydrogen on titanium aluminide alloys based on Ti3Al or α2 are now beginning to be understood. It has been established that large amounts of hydrogen are readily absorbed into these alloys, and on cooling to room temperature, virtually all this hydrogen is precipitated as a hydride phase or phases. These hydrides in turn affect mechanical properties much as in other hydride-forming materials. Extensive data now exist on these effects in the alloys based on α2. Fracture in particular is now being studied in detail, including work on micromechanisms of hydrogen fracture, which can be quantitatively compared to experiment. Needs for additional work are identified.
