摘要：

An Al3Ti alloy was immersed in hydrogen at high pressures and high temperatures. An anomalous expansion of the Al3Ti metal lattice was observed by in situ powder X-ray diffraction measurements at 625 degrees C and 10 GPa, suggesting that Al3Ti is hydrogenated to form Al3TiHx. The hydrogen content is roughly estimated to be x similar to 0.4. However, the formed hydride phase is dehydrogenated during depressurization, and cannot be recovered at ambient conditions.
