We report on novel magnetocaloric composites based on La(Fe,Si)13 particles in an amorphous metallic matrix. Hot compaction at the glass transition temperature, Tg, of the matrix prevents crack formation as commonly occurs in conventional hot-compacted La(Fe,Si)13 material. This damage can affect the magnetocaloric performance. The approach in the present paper shows that the La(Fe,Si)13 particles...
Composites of two magnetocaloric components have been prepared by melt spinning. A special nozzle modification allows to separate the melts of two different materials which solidify simultaneously as rapidly quenched composite. Two materials combinations were chosen: (a) Fe‐based amorphous materials with different Cr‐contents and (b) Fe‐based alloys with different Si‐content resulting in crystalline...
