Abstract
Abstract In the present work, the Pr9Fe65W4B22 magnets in the form of melt-spun ribbons of various thicknesses and suction-cast 1 mm diameter rods were investigated. The crystallization behavior was studied using DSC and XRD. The studies have shown that the as-cast ribbons had amorphous or partially crystalline structure depending on the thickness of the sample. On the other hand XRD pattern of the as-cast 1 mm diameter rod revealed their crystalline structure. The specimens were subjected to annealing at temperatures ranging from 923 K to 1003 K for 5 min. Heat treatment resulted in an evolution of the phase mixture that caused changes in magnetic properties of the samples. In this paper, the comparison of the phase mixture, microstructure and magnetic properties of the annealed ribbon and rod samples is presented.
