Study of the Microstructure, Mechanical, and Magnetic Properties of LaFe(11.6)Si(1.4)H(y)/Bi Magnetocaloric Composites

We have successfully synthesized LaFe(11.6)Si(1.4)H(y)/Bi composites by cold pressing together with vacuum annealing technology, and systematically investigated the microstructure, magnetism, mechanical performance, and magnetocaloric properties. LaFe(11.6)Si(1.4)H(y) particles are well surrounded b...

description We have successfully synthesized LaFe(11.6)Si(1.4)H(y)/Bi composites by cold pressing together with vacuum annealing technology, and systematically investigated the microstructure, magnetism, mechanical performance, and magnetocaloric properties. LaFe(11.6)Si(1.4)H(y) particles are well surrounded by metallic Bi, without the formation of new phase. The maximum values of the volumetric magnetic entropy change -ΔS(M) are as high as 51, 49, and 35 mJ/cm(3)K around 263 K, for the composites with 5, 10 and 15 wt % Bi contents, respectively. The maximum value of the compressive strength for LaFe(11.6)Si(1.4)H(y)/Bi composites increased continuously from 155 to 358 MPa with increasing Bi content, from 0 to 15 wt %.
