The evolution in phase composition of as-cast Fe–(31−35) at% Ga alloys during continuous heating up to 850 °C with subsequent cooling was studied. Based on the results obtained by neutron diffraction, conclusions were drawn about clearly distinguishable stages of phase formation during heating and cooling of metastable high-gallium alloys. Upon heating, the phase composition of studied alloys was found to change in a similar way, namely: BCC + Fe13Ga9 (absent in Fe–31.1 at% Ga) → BCC+ Fe13Ga9 + L12 → BCC + L12 + α-Fe6Ga5 → B2 + α-Fe6Ga5 → B2. Upon cooling, the following sequence of phase states was realized in Fe–32.9Ga and Fe–34.4 at% Ga alloys: B2 → B2 + α-Fe6Ga5 → D03 + L12 + α-Fe6Ga5. Fe–31.1 at% Ga alloy was found to be characterized by the sequence: B2 → B2 + L12 → D03 + L12 + Fe13Ga9.
