| Abstract Scope |
The presence of hydrogen within titanium can lead to embrittlement, a desirable property for facilitating comminution when producing titanium powder through a hydride-dehydride process but one that is undesirable in structural or engineering applications. As such, understanding and controlling the absorption and desorption of hydrogen in titanium is critical for successful applications of titanium materials. However, fast, precise, and accurate quantification of hydrogen content in hydrogen-rich materials like metal hydrides remains an enduring challenge. Here the capabilities and limitations of X-Ray Diffraction (XRD), Laser-Induced Breakdown Spectroscopy (LIBS), and a Quartz-Crystal Microbalance (QCM) system for hydrogen quantification are discussed for characterization of sub-stoichiometric titanium hydride (TiHx) powders in the range of 1.5 < x ≤ 2 manufactured via an equilibrium-based approach. Coupling of the methods is explored to extend and verify hydrogen quantification and improve the precision and accuracy of the measurements.
