RESUMO

Two melting systems were built to prepare Fe-Ti alloys and Mg-Ni alloys at interesting composition for hydrogen storage. Fe-Ti alloys and Mg-Ni alloys were melted by arc-electric system and electric resistance system respectively. Design, construction, assembly and use of both melting systems axe described in the present work. Initially the design criterion is considered and the composition zones of interest are selected. Both melting systems are under an argon atmosphere to prevent Ti and Mg from oxidation. The crucible, the chamber and the electrode holder are the main components of the arc electric melting system and the chamber, the furnace and the bath stirrer are the main components of the electric resistance melting system. The inert gas circuit, the cooling circuit and the power circuit are controlled by the control panel. These circuits are considered auxiliary components. Finally the operations of the melting systems are described. These melted alloys are analysed by chemical and metallographic analysis and hydrogenation tests.
