The ignition of titanium subhydride/potassium perchlorate pyrotechnic blends is influenced by the diffusion of oxygen into the titanium subhydride fuel. The following work is a preliminary study of the microstructural changes that take place during the dehydriding of titanium subhydride. Samples of TiH/sub 1/ /sub 63/ were dehydrided at temperatures between 625 and 775/sup 0/C. In the partially dehydrided samples, evidence of three different phases - ..cap alpha.. Ti (hexagonal), ..beta.. Ti (cubic), and ..gamma.. TiH/sub 2/ (cubic) - was seen. Microstructural examination of a TiH/sub 1/ /sub 15/ sample that had a layered structure is also reported. A furnace constructed for hydriding titanium foils is also described. Titanium subhydride foils having the stoichiometries TiH/sub 1/ /sub 53/ and TiH/sub 0/ /sub 87/ were prepared using this furnace.
