Abstract: The advanced magnetocaloric composites in active magnetic regenerator (AMR) are required to meet the good mechanical properties, magnetocaloric effect (MCE) and thermal conductivity. However there are challenges in the shape up and heat conduction of most of the magnetocaloric composites currently. In this paper, we reported a LaFe11.6Si1.4Hy magnetocaloric composites which was pressed together with a low melting point metal of indium (In) and the different compaction pressures of 0~800 MPa at 430K. The results show that the MCE of the composite will be deteriorated when compaction pressure exceeds 200 MPa. The In-bonded LaFe11.6Si1.4Hy composites of 0.8mm-thick sheet pressed with 100Mpa has the maximum adiabatic temperature change of 5.88K at the magnetic field change of 0~2 T.
