Compacts of Ti–6Al–4V alloy were produced via the powder metallurgy technique applying the hydride–dehydride process and hot isostatic pressing. The conditions of reversible hydride–dehydride process were controlled by chemical and X-ray diffraction analysis and scanning electron microscopy. Powders were pressed above and below the α→β transus temperature. The presence of titanium hydrides and morphology of the microstructure have the direct influence on the tensile properties and fracture toughness of the Ti–6Al–4V alloy, but the effect of microstructure is more pronounced.
