Annotation
The X-ray and electron diffraction studies show that following the stepwise annealing, 500 hours at 600°C + 30 hours at 800°C, an equilibrium $Pr_2Fe_{17}$ phase and the metastable phases, $\alpha –Рг$ and a $PrFe_5$ intermetallic compound of the $LuMn_5$ type which is a derivative of the Laves phases $MgZn_2 (С 14)$ are formed in the Pr-77 at.% Fe alloy. A scheme for rearranging $PrFe_5 (CaCu_5)$ into $PrFe_5 (LuMn_5)$ and $PrFe_5 (AuBe_5)$ has been given.
