Microstructure and Microanalysis Studies of Some Lanthanum-Magnesium Based Hydrogen Storage Alloys

摘要

Microstructures and chemical compositions of some commercial La-Mg based alloys have been investigated. The hydrogen storage alloys can be represented by the formulae La_2Mg_x, La_2Mg_(x-1)Ni and LaMg_2Ni_9 (x=12 or 17). The determination of the microstructures and phase compositions of these alloys has been carried out using scanning electron microscopy and energy dispersive X-ray analysis.
