Compositionally graded amorphous metal alloys and process for the synthesis of same
First Claim
1. A process for the synthesis of a compositionally graded substantially amorphous metal alloy of the formula
wherein M is at least one metal selected from the group consisting of Ni, Co, Fe, Cu, Mn, Pd, Ru, Si, Cr, Mo, W, Al, Sn, Zn, Cd and Ga;
M'"'"' is at least one metal selected from the group consisting of Ti, Zr, V, Nb, Ca, Mg, Y, Hf, Ta and the rare earths; and
A is at least one metal selected from the group consisting of Pd, Pt, Ir and Rh;
said process comprising;
(a) combining an M and M'"'"'-containing bulk hydrogen storage material with an A-containing material to obtain a mixture thereof;
(b) sealing said mixture in a mechanical milling device under an inert atmostphere; and
(c) milling said mixture.

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.
