Abstract
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 LaFe11.6Si1.4H1.02 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 430 K. The results show that the MCE of the composite is deteriorated when compaction pressure exceeds 200 MPa. The In-bonded LaFe11.6Si1.4H1.02 composite sheet with a thickness of 0.8 mm pressed with 100 MPa has the maximum adiabatic temperature change of 5.88 K at the magnetic field change of 0∼2 T.
