Selecting, shaping and thermal analysis of Y2Fe17xCox series for magnetocaloric heat conversion
Résumé
In this work, we first present the composition dependence of the magnetocaloric properties in the Y2Fe17xCox series. Then, we show preliminary results on our shaping works. In order to use the Y2Fe17xCox compounds in magnetocaloric heat conversion systems, we applied powder metallurgy technics at a semi industrial scale to shape it. That involves milling, sintering, and heat treatments. Finally, the emphasis has been laid on the thermal properties of the sintered material, considering their decisive influence on the performance of the system.
