1. A nanopowder made by a process comprising:
reacting Ti(BH4)3 with LiAlH4 in an aprotic solvent while being sonicated to produce nanoparticles comprising titanium, boron, and hydrogen;
wherein the molar ratio of Ti(BH4)3 to LiAlH4 is from 1:1 to 1,000,000:1; and
annealing the nanoparticles under a vacuum;
wherein the nanopowder comprises at least 90 wt. % elemental amorphous titanium and elemental amorphous boron.
