The phase content, microstructure, the thermal stability, kinetics of hydrogen desorption from the MgH<sub>2</sub> hydride phase of the obtained MAs were studiedby using XRD, SEM, TDS methods. It has been established that the addition of Ti + Y and Ni + Y to magnesium leads to significant improvement in the kinetics of hydrogen desorption from the&nbsp; MgH<sub>2</sub> hydride phase, which is evidenced by a significant reduction (in 6 and 15 times)in the time of release of all hydrogen from MA1 and MA2, respectively. Due to, Ti, Ni,Y alloying, the decrease in the thermodynamic stability of MgH<sub>2</sub> is not found.</p> ER -
