• 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 %.
