Abstract

We performed an experimental study on the structural and magnetocaloric properties of PLA-based composite filaments of Mn_0.5Fe_0.5Ni_0.95Cr_0.05Si_0.95Al_0.05. X-ray diffraction patterns confirmed that the as-cast powder and the extruded filament composites exhibited the mixed hexagonal and orthorhombic crystal structures at room temperature. The dc magnetization data showed that all samples exhibited the first-order magnetic phase transition near room temperature. The entropy changes evaluated from the isothermal magnetization data peaked at 301 K for the powder sample and 322 K for the filament with 57 wt. % powder during warming. For a field change of 5 T, peak entropy changes of −5.5 J kg⁻¹ K⁻¹ and −1.2 J kg⁻¹ K⁻¹ were observed for powder and filament, respectively. The results suggested that PLA-composite additive manufacturing may be a promising technique for producing magnetocaloric coolants from brittle materials.
