Synthesis and Characterization of Nanostructure Magnesium Base Alloy by Mechanical Alloying for Hydrogen Storage Application

Abstract:

Hydrogen storage is a key enabling technology for the advancement of hydrogen and fuel cell power technologies in transportation, stationary, and portable applications. The hydrogen transport from surface to the core of the metal powder particles is an important step during a hydrogenation reaction. Therefore, the hydrogen desorption kinetics are required for a complete understanding of the hydrogenation mechanism. In this present work, Mg-Ni-Nb systems were synthesized by mechanical alloying under optimized milling parameters (milling speed, milling time). The structural evolution (nanostructure, formation of intermetallic phases, etc) during ball milling was studied by X-ray diffraction. The activation energy of the mechanical alloyed powders was studied for Mg-Ni-Nb systems. Hydrogenation and dehydrogenation studies were carried out and understood the hydrogen interaction with Mg based alloys.
