The isothermal sections of the phase diagram of the V–Fe–Sb ternary system have been constructed at 870 and 1070 K by means of X‐ray and electron‐probe microanalyzer (EPMA) analyses over the whole concentration range. The existence of the one ternary phase, VFeSb, with MgAgAs‐ and Ni 2 In‐type structures was observed at 870 and 1070 K, respectively. The solid solution formed based on the binary Fe 2– x Sb (Ni 2 In‐type) compound reaches up to 12 at.‐% of V at 870 K and 40 at.‐% at 1070 K, respectively. Differential scanning calorimetry (DSC) analysis, magnetic susceptibility measurements, and electronic structure calculations showed the absence of a VFeSb polymorph phase transition and indicate that the hexagonal phase is part of the V y Fe 2– x Sb solid solution.
