Five Fe-Ga samples with gallium content ranging from 13.2 to 19.7 at. % are studied in this paper. X-ray phase analysis is carried out for the certification of the phase composition of the initial samples; in order to find differences in the chemical composition inside the grains and in the near-border areas, elementary analysis of individual structure sections is carried out. It is demonstrated that in this alloy there is a distinct brittle fracture. To study the mechanical properties and to reveal their behavior with increasing Ga content, it is proposed to use a nanoindentation system. An increase in microhardness and a decrease in the plastic work of indentation with increasing Ga content are shown.

Acknowledgements: The work was performed within the state assignment from FASO Russia (Magnet, No. АААА-А18-118020290129-5) and partially supported by the RFBR (project No. 18-03-00623) and UB RAS Complex Program No. 18-10-2-5. The experimental results were obtained with the use of the equipment of the Testing Center of Nanotechnology and Advanced Materials collective use center.
