The potential for the fabrication of highly porous commercially pure titanium, zirconium, and a binary Ti–10% Zr alloy by cold compaction and vacuum sintering of hydride TiH2 and ZrH2 powders is evaluated. Porous materials are obtained without the use of pore-forming additives, which can negatively affect the purity of the final materials, while the use of initial hydride powders contributes to a decrease in the impurity content. The main regularities of the microstructure formation and the features of the porous structure depending on the size of the hydride powders, compaction pressure and sintering temperatures are established. Materials with a total pore volume of about 30% and a significant proportion of open pore channels with a diameter of 20 μm to 60–80 μm are obtained. Such porous materials are promising for use in gas and liquid filtration systems, as well as getters.
Key words: titanium and zirconium hydrides, sintering, porous materials, microstructure.
