ABSTRACT:
Disclosed is an improved metastable, multi-component, multi-phase hydrogen storage alloy material formed by rapid solidifcation from a melt. The improved metastable hydrogen storage alloy is characterized by a refined grain size of Approximately 1 micron or less, and the reduction, or elimination of deleterious phases.
The microstructure of the alloy is relatively disordered, and each phase of the material comprises less than 50 atomic percent vanadium and chromium combined. The nominal composition is:
