TI-V-CR-MN-MG ALLOY FOR THE HYDROGEN STORAGE AND THE METHOD OF PREPARING THE SAME

摘要

PURPOSE: Ti-V-Cr-Mn-Mg alloy for hydrogen storage and a preparation method thereof are provided to occlude more hydrogen by substituting a part of V element with Mn and adding Mg in BCC solid solutions for hydrogen storage. CONSTITUTION: Ti-V-Cr-Mn-Mg alloy for hydrogen storage comprises Ti 33~35 weight%, V 20~27 weight%, Cr 37~39 weight%, Mn 1~8 weight%, and Mg 1~5 weight%. The Ti-V-Cr-Mn-Mg alloy is obtained by substituting a part of V element with Mn and adding Mg in BCC solid solutions for hydrogen storage, wherein Ti, V, Cr, and Mn are ball-milled and Mg is embedded. The hydrogen occluding rate of the Ti-V-Cr-Mn-Mg alloy at the room temperature is 3.46~3.64 weight%.
