RE-Dependent Phase Transformations and Structures in Fe&sub(73)Ga&sub(27)-RE Alloys / B.Yerzhanov, A.M.Balagurov, B.Mukhametuly, N.Yu.Samoylova, S.V.Sumnikov, V.V.Palacheva, I.S.Golovin. – Text : electronic // Applied Physics A. – 2025. – Vol. 131, No. 5. – P. 356. – URL: https://doi.org/10.1007/s00339-025-08432-y. – Bibliogr.: 22.
The phase compositions and structural transformations in the Fe&sub(73)Ga&sub(27) alloy with trace amounts (~ 0.1 − 0.2 at%) of rare earth (RE) elements (Er, Pr, Sm, Tb, Yb) have been analyzed in neutron diffraction experiments performed over a wide temperature range. In the initial as-cast state, all Fe-Ga-RE alloys, except for the composition with Yb, are in a metastable state with the structure of the D0&sub(3) phase. In the alloy with Yb, a noticeable amount (17%) of the L1&sub(2) phase is present even in the initial state. When the alloys are slowly heated to 900 &sup(o)C (2 &sup(o)C/min), the structural transformations generally occur similarly to the initial Fe&sub(73)Ga&sub(27) alloy. Upon subsequent cooling to room temperature, an equilibrium L1&sub(2) phase is formed in all alloys with RE elements and suppression of the HCP-phases (A3/D0&sub(19)) formation is observed, which is especially strong in the compositions with Pr, Sm and Tb, whereas in the Fe&sub(73)Ga&sub(27) alloy the L1&sub(2) and D0&sub(19) phases are present in approximately equal proportions. The microstructure of the alloys, with the exception of Fe-Ga-Tb, is homogeneous in the initial state with large (> 3000 Å) characteristic sizes of coherent scattering domains (CSDs) and a small (< 0.001) level of microstrains. In the alloy with Tb, the microstructure is a matrix of a partially ordered B2 phase with dispersed embedded clusters of the ordered D0&sub(3) phase with characteristic CSD sizes of ~ 400 Å. No traces of the L6&sub(0) tetragonal phase were found in the neutron diffraction patterns of the studied Fe&sub(73)Ga&sub(27)-RE alloys.
