Formability and magnetic properties of Dy-Co binary amorphous alloys
Source abstract
Abstract
In this study, binary Dy-Co ribbons were synthesized by a conventional melt-spinning approach and glassy ribbons were successfully obtained within the compositional range Dy50Co50 to Dy68Co32. The glass formability and magnetic properties of these amorphous alloys were examined. The compositional dependence of glass formability, Curie temperature and magneto-caloric response of the DyxCo100-x (x=50, 55, 60, 65 and 68) amorphous alloys, as well as the mechanism involved, were determined.
