Hydriding of TiMo alloys at high hydrogen pressures

详细

We studied the interaction of Ti_0.40Mo_0.60 and Ti_0.34Mo_0.66 alloys with hydrogen and obtained hydrogen desorption isotherms at pressures of up to 250 MPa. At high hydrogen pressures, we observed the formation of Ti_0.40Mo_0.60Н_1.1 and Ti_0.34Mo_0.66Н_0.8 hydride phases. According to X-ray diffraction data, the hydrides consisted of phases with a body-centered cubic and face-centered cubic (CaF₂ structure) lattices. The structure of the deuteride based on the Ti_0.40Mo_0.60 alloy was studied by neutron diffraction. We identified the sites occupied by deuterium atoms and determined their occupancies.
