Abstract
A composite object for the production of hydrogen from water-reactive aluminum may include a first portion including an aluminum alloy having a non-recrystallized grain structure, and a second portion including an activation metal corrodible to the aluminum alloy, wherein the second portion and the first portion are coupled to one another with the activation metal of the second portion in contact with the aluminum alloy of the first portion at a plurality of points of contact stress, and the activation metal of the second portion is penetrable into the non-recrystallized grain structure of the aluminum alloy of the first portion via the addition of heat.
Claims15
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.
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 the first article is a first filament and the second article is a second filament, and cold-working the first article and the second article includes forming the composite object as one or more of a twist, a braid, or wire wool including the first filament and the second filament.
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;
- 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;
- and
- energizing the composite object to penetrate at least a portion of the activation metal from the second portion of the composite object into a grain structure of the aluminum alloy in the first portion of the composite object to form activated aluminum.
