The properties of rapidly solidified ribbons of Pr₉Fe_{50+x}Co₁₃Zr₁Nb₄B_{23-x} (where x=2, 5, 8) alloys annealed at temperatures ranging from 923 K to 1033 K were investigated. The heat treatment of the fully amorphous as-cast ribbons led to the simultaneous crystallization of the hard magnetic Pr₂(Fe,Co)₁₄B, the soft magnetic α-Fe and the paramagnetic Pr_{1+x}Fe₄B₄ phases. However, the crystallization of the α-Fe phase took place as the second crystallization event at higher temperatures for the x=8 alloy. The Rietveld analysis of the X-ray diffraction patterns was used to calculate the crystallite sizes of constituent phases. Additionally, using PONKCS method the weight fractions of crystalline and amorphous components were quantified. For all alloy compositions the temperature dependencies of magnetic parameters were determined from the hysteresis loops.
