| Abstract Scope |
Titanium hydrides have broad use in applications such as titanium powder production, powder sintering processes, hydrogen storage, and as fuels in pyrotechnic and propellant formulations. For these applications, both hydrogen content and transport phenomena directly impact material performance. As such, understanding and controlling the absorption and desorption of hydrogen in titanium is critical for successful application and manufacturing of titanium hydride materials. However, characterization of hydrogen content and transport phenomena in hydrogen-rich materials like metal hydrides remains an enduring challenge. Here the synergistic application of Laser-Induced Breakdown Spectroscopy (LIBS) and a novel high-temperature Quartz-Crystal Microbalance (QCM) system is explored for in-situ characterization of sub-stoichiometric titanium hydride (TiHx) powders in the range of 1.5 < x ≤ 2 manufactured via an equilibrium-based approach. Capabilities of the methods for assessing pressure-composition-temperature (PCT) curves, diffusion processes, and bulk hydrogen content will be discussed. |
