Abstract (en)

[origin: WO2010121977A1] The invention relates to the field of materials science and materials physics and concerns a magnetic alloy material, which can be used, for example, as a magnetic cooling material (magnetocaloric material) for cooling purposes or for energy generation purposes, and a process for the production thereof. The aim of the present invention is to provide a magnetic alloy material which has comparable magnetic and/or magnetocaloric properties and improved mechanical properties compared to prior art materials. This aim is achieved by a magnetic alloy material which displays a magnetocaloric effect and has a foam-like structure with an open porosity of from 1% to 50% and/or a closed porosity of at least 1% or in which particles of the magnetic alloy material are embedded in a matrix material having a higher ductility than the magnetic alloy material.
