In the present study the rapidly quenched Pr9Fe50 + xCo13Zr1Nb4B23 - x (x = 0, 2, 5, 8) alloy samples produced in a form: of 100 mm2 plate of various thicknesses were investigated. The X-ray diffraction revealed changes in the phase constitution of as-cast samples depending on the alloy composition and plate thickness. The presence of hard magnetic Pr2(Fe,Co)14B phase was observed in 0.5 mm thick plates of the x = 8 alloy, while fully glassy structure was shown in 0.5 mm thick plates of the x = 0 alloy. It was shown in the present paper that magnetic properties of annealed samples originated from different microstructure of as-cast samples.
