Fe-Sn (Iron-Tin) H. Okamoto The equilibrium phases of the Fe-Sn phase diagram are: (1) the liquid phase, L, encompassing a miscibility gap; (2) the fcc terminal solid solution, (gFe); ( 3) the bcc terminal solid solution, (aFe); (4) hexagonal Ni2In-type Fe5Sn3; (5) rhombohedral Fe3Sn2; (6) hexagonal CoSn-type FeSn; (7) tetragonal Al2Cu-type FeSn2; (8) the tetragonal terminal solid solution, (bSn); and (9) the diamond cubic terminal solid solution, (aSn). The Fe-Sn phase diagram has been investigated extensively by thermal analysis [ 07Isa, 25Wev, 26Wev1, 26Wev2, 31Edw], metallographic observations [07Isa, 25Wev, 26Wev1, 26Wev2, 31Edw, 34Jon, 71Jol], X-ray and lattice parameter measurements [33Ehr, 43Ehr, 45Nia, 72Spe, 73Pre, 74Nag, 86Sin], chemical and microanalyses [49Cam, 57Kak, 64Mil, 67Hil, 74Tre1, 81Yam], and thermodynamic measurements [69Mor, 81Ari, 83Yam, 87Nun]. Because of slow transformations between solid phases, some of the thermal analysis data at low temperatures reflect nonequilibrium transitions. The assessed miscibility gap in the liquid phase is according to [87Nun]. The g loop is based on the X-ray investigation of [72Spe]. The (aFe) phase boundaries are based on thermal [07Isa], metallographic [63Jan], lattice parameter [73Pre, 74Nag], activity [81Ari], and EPMA [74Tre1, 81Yam] investigations. [63Jan] found Fe5Sn3 at 38 at.% Sn (Fe-rich side of Fe3Sn2) instead of "g" at 44 at.% Sn reported by [33Ehr], [43Ehr], [45Nia], and [60Asa]. X-ray diffraction measurements by [66Yam] supported the nonexistence of pure "g" ( NiAs type according to [43Ehr]) at 44 at.% Sn. In accordance with [63Jan], [ 66Yam] observed Fe5Sn3 instead of "g", but only at above 760 C. [70Dje] found Fe5Sn3 between 37 and 37.5 at.% Sn in the temperature range 910 to 780 C. [ 74Tre2] reported similar temperature range 910 to 782 C. [81Yam] found in a 17 at.% Sn alloy equilibrated at 850 C for 21 days that Fe5Sn3 with 37.2 at.% Sn is in equilibrium with (aFe). These recent reports appear to suggest that Fe5Sn3 was recognized as "g" in earlier investigations. The existence of "Fe3Sn" was reported by [07Isa], [25Wev], and [43Nia]. The temperature range of existence is between 850 and 750 C [69Bas], between 810 and 760 C [71Jol], or between 838 [73Tre] and 765 C [74Tre2]. However, a high-temperature X-ray investigation showed that Fe3Sn is an oxygen stabilized phase [86Sin]. 07Isa: E. Isaak and G. Tammann, Z. Anorg. Chem., 53(1), 281-297 (1907) in German. 25Wev: F.
