Measures Improving Magnetocaloric Properties of GdSiGe Room-Temperature Magnetic Refrigerating Alloy |
| |
| Abstract: | GdSiGe is a kind of magnetic refrigerating alloy having the best magnetocaloric p roperties by now. Some work done in our laboratory and by other researchers in the world abou t improving the magnetocaloric proprieties of the GdSiGe alloy were introduced, from the point of view of alloying, melting, solidification, heat treatment, nan ometrization, co mposite. It aims at enhancing the entropy change and the adiabatic temperature c hange. It will be helpful for applying the GdSiGe magnetic refrigerator alloy to the room magnetic refrigeration. |
