TI-NB-CR HYDROGEN STORAGE ALLOY AND THE METHOD FOR PRODUCING THE SAME

摘要

The present invention provides a Ti-Nb-Cr-based hydrogen storage alloy capable of significantly increasing the hydrogen storage amount, and a method for producing a Ti-Nb-Cr-based hydrogen storage alloy by a simple process that is easy to control a reactive atmosphere. The hydrogen storage alloy of the present invention is characterized in that 1 wt% to 5wt% of Nb is added to the Ti-Cr-based hydrogen storage alloy. Ti-Nb-Cr-based hydrogen storage alloy production method of the present invention comprises the steps of preparing a Ti, Nb, Cr raw material powder according to the target composition; Charging the raw powders together with steel balls into a container and pressurizing nitrogen; And a mechanical alloying treatment while rotating the vessel.;Hydrogen storage alloy, planetary ball milling, Ti-Cr alloy, Ti-Nb-Cr alloy, Laves phase
