The monolithic and composite titanium aluminides can play a major role as materials of construction of advanced systems such as the National Aerospace Plane (NASP). However there are concerns that these elevated temperature/light weight materials may degrade significantly in the pressure of hydrogen - the fuel for the NASP. This paper reviews the current state of knowledge of the interaction of hydrogen with both the Ti3Al (α2) and TiAl (γ) compositions. It is concluded that while there is much cause for concern, our knowledge of the interaction is far from complete.
