Abstract
The present invention is directed to a process for the synthesis of a compositionally graded substantially amorphous metal alloy comprising: (a) combining a bulk hydrogen storage material with an A-containing material to obtain a mixture thereof; (b) sealing the mixture in a mechanical milling device under an inert atmosphere; and (c) milling the mixture. Alloys produced by this process are useful for the efficient cyclic storage and release of hydrogen in large quantities without becoming embrittled, inactivated or corroded.
