摘要: A method of producing a clad sheet article having superplastic properties, and the resulting clad sheet article. The method involves producing a cladding layer onto at least one rolling face of a core ingot made of a metal having superplastic properties, preferably by co-casting, to form a clad ingot and then rolling said clad ingot to produce a sheet article. The core ingot includes an element that diffuses from an interior of the ingot to a surface at superplastic forming temperatures thereby deteriorating surface properties of the ingot. The cladding layer is provided with an element (dopant) that reacts with the element of the core to reduce the ability of the element to diffuse through the cladding layer.

摘要: An aluminum battery comprises an aqueous alkaline electrolyte and an anode which is an alloy of aluminum containing magnesium and/or calcium. Tin is present in the electrolyte (as stannate at a concentration of 0.001 to 0.01 M) and/or in the anode (at a concentration of at least 0.005%). The batteries operate at high coulombic efficiency at both high and low current densities. Preferred conditions of operation comprise drawing current at an average current density of 5 to 400 mA/cm.sup.2 of anode surface for at least one hour, and introducing seed crystals into the electrolyte to aid precipitation of aluminum values from the electrolyte.

摘要: A bipolar cell unit is described for use in a metal/air battery, e.g. an aluminum/air battery. Each bipolar cell unit comprises (a) an air cathode having opposed major surfaces, one of the surfaces being exposed to air and the other of the surfaces being adapted for exposure to electrolyte, (b) a metal anode comprising a metal plate having opposed major surfaces with one plate major surface positioned in spaced juxtaposed relation to the cathode surface exposed to air thereby forming an air gap between the anode and cathode, (c) structural means for connecting the air cathode to the anode plate whereby the air cathode is supported by the anode plate such that air is permitted to move through the air gap while electrolyte is excluded and (d) an electrical connection between the anode and cathode.
