Fe-Mn-Ti alloys located along the line joining TiMn₂ and TiFe₂ and in the isopleth with 14 at.% Fe between 33.3 and 45 at.% Ti have been studied using DTA and X-ray diffraction. The polythermal section TiMn₂-TiFe₂ has been constructed. It is quasibinary with a cigar-type fusion diagram. The composition dependence of the crystallographic cell parameters obeys the Vegard rule. The existence of a sharp bend on the Ti-rich boundary of the Ti(Mn,Fe)₂ field at 14 at.% Ti was not confirmed.
