Influence of Rapid Quenching on Magnetocaloric Effect of Y2(Fe,Mn)17 Intermetallic Compounds
The melt-spun Y2(Fe,Mn)17 ribbons were synthesized by rapid quenching from the melt. The phase composition, crystal structure and magnetocaloric effect (MCE) in low-cost iron-based pseudo-binary Y2(Fe,Mn)17 ribbons were investigated respectively by using x-ray diffraction and direct measurements of MCE. It was found that crystal structure of the as-spun ribbons retains hexagonal Th2Ni17-type because of the weak glass-forming ability. The Y2Fe14Mn3 and Y2Fe13Mn4 nanostructured ribbons demonstrate higher MCE compare to polycrystalline alloys.
