Abstract
A series of diffraction experiments on a number of alloys similar in composition to stoichiometric Fe3Me with Me = Al, Ga, Ge were performed on X-ray, synchrotron, and neutron radiation sources. In the temperature range (20–1100 K), the structural, magnetic and microstructural characteristics of alloys were determined and their temperature evolution during continuous slow heating and subsequent cooling was studied. The information available in the literature on metastable and equilibrium states of alloys at elevated temperatures is clarified and specified, and their comparative analysis is performed. The identity of the temperature behavior of the alloys was observed at T < 100 K. The search for the tetragonal L60 phase, the formation of which in Fe–Ga alloys is considered as the main reason for the sharp increase in the magnetostriction constant, did not lead to a positive result.
