METHOD FOR PRODUCING METAL-BASED MATERIALS FOR MAGNETIC COOLING OR HEAT PUMPS

摘要

The process for preparing metal-based materials for magnetic cooling or heat pumps comprises the following steps: a) reacting chemical elements and/or alloys in a stoichiometry which corresponds to the metal-based material in the solid phase and/or liquid phase, b) if appropriate converting the reaction product from stage a) to a solid, c) sintering and/or heat treating the solid from stage a) or b), d) quenching the sintered and/or heat treated solid from stage c) at a cooling rate of at least 100 K/s.
