资源简介：
LaFe11.6Si1.4 samples were hydrogenated at the initial hydrogen-filling pressure of 0.6 MPa and different temperatures (from 393 K to 478 K). The hydrogen absorption kinetics performance, magnetocaloric effect and Curie temperature (TC) of these alloys were investigated. The results show that all samples have excellent hydrogen absorption kinetics performance and the hydrogen saturation time of these samples decreased from 45 min (at 393 K) to 4 min (at 478 K).The magnetic entropy changes were 16.27 J/kg.K (before hydrogen absorption), 12.2 J/kg.K (at 393K), 10.48 J/kg.K (at 423K), 7.81 J/kg.K (at 453) and 10.64 J/kg.K（at478K,respectively. The Curie temperature varied from 325.7Kfor an absorption temperature of 393Kto 276.8Kfor an absorption temperature of 478K.
