The MAX-phase Ti3AlC2 was synthesized by sintering method. The study of sorption properties of the sample was carried out under conditions continuous heating. It was established that desorption of hydrogen begins at a temperature of ~ 210 °С. After complete desorption, the sample was re-heated in an atmosphere of hydrogen. It was found that Mg-5 wt% Ti3AlC2 composite begins absorb hydrogen at a temperature of ~ 76 °С. As a result of cycling, the temperature of desorption has shifted towards lower values ~ 186 °C.

The possibility of synthesizing the Ti3AlC2 and Ti2AlC MAX phases by SPS (spark-plasma sintering) consolidation of the charge obtained as a result of mechanoactivation and a charge obtained by HVED (high-voltage electric discharge) of processing titanium and aluminum powders in kerosene has been experimentally studied. The influence of the charge activation method on phase formation and physical properties of consolidated materials is shown.
