1. A method of processing material for forming activated aluminum reactable with water to produce hydrogen, the method comprising:
positioning a first article in contact with a second article, the first article including an aluminum alloy, the second article including an activation metal, and the aluminum alloy is corrodible by the activation metal; and
cold-working the first article and the second article together with one another to form a composite object including the aluminum alloy in a first portion and the activation metal in a second portion, wherein the activation metal of the second portion is energizable to penetrate into a cold-worked non-recrystallized grain structure of the aluminum alloy of the first portion, wherein cold-working the first article and the second article together with one another forms at least about 20 percent plastic strain in the aluminum alloy of the first portion of the composite object.
