Phase transitions in TiD<sub>approximately 0.75</sub> subjected to high-pressure treatment were investigated by simultaneous real-time measurements of neutron diffraction and small-angle neutron scattering. The neutron spectra were taken on heating the samples in the temperature ranges 100 to 300 K and 300 to 760 K followed by cooling to 430 K. A sequence of structural transitions was observed, which involves seven different phases and intermediate states with the hexagonal close-packed, face-centred cubic, face-centered orthorhombic or body-centred cubic metal sublattices and hydrogen atoms distributed on octahedral or ordered/disordered tetrahedral interstices.
