The mechanical properties and magnetocaloric effect (MCE) of bonded La(Fe, Si)13 hydrides have been studied in detail. strength increases with increasing the grade epoxy resin from E-20 to E-51. This occurs because more pores boundaries are filled high since epoxide content degree crosslinking reduces viscosity shrinkage resin. compressive reaches 162 MPa for LaFe11.7Si1.3C0.2H1.8 3 wt. % E-51, which is 35% higher than that bulk LaFe11.7Si1.3C0.2 compound (120 MPa). mass ΔSM values remain...
Magnetic properties and magnetocaloric effect (MCE) of intermetallic HoNiSi compound have been investigated systematically. It is found that exhibits antiferromagnetic (AFM) state below the Néel temperature TN 3.8 K, which quite close to liquid helium (4 K). A giant MCE without hysteresis loss observed in HoNiSi, related field-induced first-order metamagnetic transition from AFM ferromagnetic states. For a magnetic field change 2 T, maximum values entropy (−ΔSM) adiabatic (ΔTad) are 17.5...
The effects of Y on the phase composition and magnetocaloric effect in La1−xYxFe11.5Si1.5 compounds were studied. Y2Fe17-type α-Fe appear annealed when x ≥ 0.07 due to small solid solubility NaZn13 phase. Y2Fe17 obstructs formation 1:13 phase, leading decrease magnetic entropy changes. But for < 0.1, exhibit high changes low hysteresis loss compared with that LaFe11.5Si1.5. Consequently, (x 0.1) are useful realize large smaller loss.
