Microstructural investigations of rare-earth transition-metal-based magnetocaloric materials for near-room-temperature applications
Magnetocaloric materials are promising materials for magnetic refrigerators which would substitute present compressor refrigerators. They work on the principle of the magnetocaloric effect (MCE), where the magnetocaloric material increases its temperature when exposed to an external magnetic field. These new type of refrigerators are energetically more efficient and environmentally friendly. …
Hydrogen absorption in Ti-Zr-Ni alloys
Our research focused on the formation of Ti40Zr40-xNi20Cux (x=3, 5), Ti45Zr38-xNi17Cux (x=3, 5), Ti53Zr27-xNi20Cux (x=3, 5) and Ti58Zr24-xNi18Cux (x=3, 5) icosahedral (i-phase) quasicrystals by three different techniques and their subsequent characterization and high-pressure hydrogenation. The quasicrystals of this system are thermodynamically stable and they have a relatively good affinity for …
