The work presents the results of investigation of effect of changes in chemical and phase composition on hardening of magnesium alloy at its alloying with gallium. The produced experimental ingot was examined by the methods of X-ray phase and spectral analysis. It is shown that as a result of alloying of magnesium alloy with gallium the intermetallic phase Mg5Ga2 is formed. Mechanical testing by the method of microindenting showed a significant increase in Young modulus from 42 up to 73…110 GPa and microhardness from 1.2 up to 2.0…4.5 GPa. Ref. 8, Figures 7.
