Abstract
The present invention is directed to a process for the synthesis of a compositionally graded substantially amorphous metal alloy comprising: PA1 (a) combining a bulk hydrogen storage material with an A-containing material to obtain a mixture thereof; PA1 (b) sealing the mixture in a mechanical milling device under an inert atmosphere; and PA1 (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.
