Abstract
Two new species of materials were studied by neutron radiography: lithium-bearing ceramics and glasses, and titanium aluminide alloys. Various types of discontinuities, including voids and bulk density reduction, were detected. Hydrogen absorption by a titanium aluminide alloy was measured as a function of exposure time, with ‘as received’ and polished samples. The interaction of hydrogen with the metal lattice is likely to cause embrittlement, leading to material failure by the loss of tensile ductility. The effects of a rough surface and an oxide layer on the rate of hydrogen absorption were observed.
