ABSTRACT:
Titanium-containing hydrogen storage alloys with a Laves phase composition AB.sub.2 are made in which the A component is titanium and possibly an element from the start of the transition metal groups of the Periodic Table. According to the invention a titanium-free prealloy is first formed and this prealloy is comminuted and smelted again with addition of titanium and possibly zirconium in a second vacuum furnace stage. The latter melt is then deoxidized with cerium mischmetal. Hydrogen storage capacities of about 2% by weight and above that conventionally obtained can be made.
