| Research Abstract |
Using a new custom-made single mode microwave irradiation machine (operated at 915 MHz) which allows electrical and magnetic field separation and is equipped with an alumina (Al_2O_3) press, production of the large-scale samples (30 mm in diameter and larger) of the metallic glasses, crystal-glassy and glassy-polymer composites as well as nanocrystalline dispersed glassy composites has been carried out in a vacuum and inert atmosphere. A theoretical explanation of microwave heating of metallic powders in microwaves using effective medium approximation for core-shell composite has been proposed. The hydrogen absorption behaviour, the structure change and dehydrogenation properties for metal hydrides and complex hydrides by microwave irradiation were investigated.
