A method for producing a metal-based powder that is used in metal additive manufacturing, the method comprising: melting alloy metal precursors at a temperature above a liquidus temperature thereof until all alloy metal precursors are in liquid state, to produce a molten alloy; casting the molten alloy by transferring the molten alloy into a caster; cooling the molten alloy to a temperature of at least below the solidus temperature, at a cooling rate above about 50° C./s, to produce a cast alloy with a low density of precipitates; remelting the cast alloy with a low density of precipitates to produce a melted alloy; and forming the metal-based powder from the remelted alloy.

The present invention relates to a method for the economic production of light structural components with high flexibility in the geometry attainable. It also relates to the material required for the manufacturing of those parts. The method of the present invention allows a very fast manufacturing of the parts. The method of the present invention also allows the economic manufacturing of components with intricate internal geometries (such as for example cooling or heating circuits).

Anode and cathode electrodes of a rechargeable lithium-ion battery are manufactured using metal foam. This lithium-ion battery with the metal-foam electrodes can have pores coated or filled, or both, with high-capacity active materials for greater energy density, better safety, improved power, and longer cycle life. Aluminum (or nickel) and copper metal-foam electrodes are manufactured using space-holder and freeze-casting methods. An anode can be filled with a graphite or silicon slurry, or a combination. A cathode can be filled with a lithium cobalt oxide (or other higher-capacity active materials) slurry. The relatively thick metal-foam electrodes are attached to the cell, separated by a separator, and wetted by an electrolyte, forming a high-capacity secondary battery. The battery will have higher density, improved power, and good cycle life.

Methods for fabricating an interconnect for a fuel cell stack that include providing a protective layer over at least one surface of an interconnect formed by powder pressing pre-alloyed particles containing two or more metal elements and annealing the interconnect and the protective layer at elevated temperature to bond the protective layer to the at least one surface of the interconnect.
