| The present studies are focused on the rapidly solidified ribbons of the Pr9Fe56Co13Zr1Ti3B18 alloy. The ribbons were obtained by melt spinning technique at various linear velocities of the copper roll surface, thus leading to their various thicknesses. The X-ray diffraction studies revealed differences in the degree of crystallinity in the as-cast state that depends on the thickness of the ribbon. It was also shown that the surface of the thickest ribbon being in contact with copper roll was amorphous while the free surface was partly crystalline. The aim of the present work was to determine the influence of the initial structural state of the ribbons on the crystallization processes during annealing. The annealing conditions were set base on the DSC studies. These structural characteristic features were used to explain the changes of magnetic properties of studied specimens. |
