Abstract Scope This study is a systematic work on powder sintering involving TiH2 under vacuum sintering in the Ti-Ni, Ti-Al and pure TiH2 powder systems, using neutron diffraction, TEM and neutron radiography. The phase transformation, microstructure, densification behavior and hydrogen concentration were studied and compared within various powder systems. It was found sintering involving TiH2 behaves differently with reference to the system. Unlike enhanced densification by the use of TiH2 as commonly reported in literature, this report shows an adverse effect of TiH2 on powder densification in the Ti-Ni system. Within the Ti-Ni system the Ni particle acts as an obstacle to the newly-born Ti densification after its dehydrogenation, while it is beneficial for neck-sintering or takes place simultaneously with the Al melting in the pure TiH2 or Ti-Al systems respectively, favoring final densification. The difference raised by dehydrogenation was discussed based on either in situ or ex situ results.
