This article considers the phase structure and physical and chemical properties of alloys of systems Pr-Fe-Co, Pr-Co-Re and Pr-Fe-Re at 870K. The phase equilibrium in the Pr-Co-Fe,         Pr-Co-Re, Pr-Fe-Re systems is studied by the methods of physical-chemical analysis. The research results are presented in the form of isothermal cross-sections of triple phase diagrams at 870K for praseodymium concentration up to 33,3 at.%. Continuous solubility occurs between binary intermetallic compounds PrCo₂,  PrFe₂, Pr₂Co₁₇ and Pr₂Fe₁₇  in the system of Pr-Co-Fe at 870K. Besides, the magnetic properties such as saturation magnetization, residual induction and coercive force of the intermetallic compounds of PrCo₅ and Pr₂Me₁₇ doped with iron and rhenium in the system of Pr-Co-Fe, Pr-Co-Re and Pr-Fe-Re are studied along with the effect of rhenium on the magnetic properties of intermetallic compounds of praseodymium with iron and cobalt.
