Shock compression of titanium hydride and titanium, tantalum, and zirconium deuterides

This paper presents the results of an experimental study of shock compression of titanium hydride $\mathrm{TiH}_2$ and the deuterides of zirconium $\mathrm{ZrD}_2$, tantalum $\mathrm{TaD}_{0.8}$, and titanium $\mathrm{TiD}_2$, $\mathrm{TiD}_{1.6}$, and $\mathrm{TiD}_{1.1}$ in the pressure range $30$–$220$ GPa. The synthesis of titanium and zirconium deuterides from titanium and zirconium powders and tantalum deuterides from tantalum rods is described. The Hugoniots of deuterides and hydrides were determined using the well-known reflection method. Shock-wave compression was performed using shock-wave generators with explosive charges of different power. A description of the obtained experimental data using simple equations of state is proposed.
