Abstract

Uranium-rich niobium and niobium-zirconium alloys possess a characteristic known as shape memory effect wherein shaped articles of these alloys recover their original shape when heated. The present invention circumvents this memory behavior by forming the alloys into the desired configuration at elevated temperatures with "cold" matched dies and maintaining the shaped articles between the dies until the articles cool to ambient temperature.

Method for fabricating uranium alloy articles without shape memory effects

Patent Banker, J G

Uranium-rich niobium and niobium-zirconium alloys possess a characteristic known as shape memory effect wherein shaped articles of these alloys recover their original shape when heated. The present invention circumvents this memory behavior by forming the alloys into the desired configuration at elevated temperatures with cold matched dies and maintaining the shaped articles between the dies until the articles cool to ambient temperature.
Method of fabricating thin-walled articles of tungsten-nickel-iron alloy

Patent Hovis, Jr., Victor M. (Kingston, TN); Northcutt, Jr., Walter G. (Oak Ridge, TN)

The present invention relates to a method for fabricating thin-walled high-density structures oftungsten-nickel-iron alloys. A powdered blend of the selected alloy constituents is plasma sprayed onto a mandrel having the desired article configuration. The sprayed deposit is removed from the mandrel and subjected to liquid phase sintering to provide the alloyed structure. The formation of the thin-walled structure by plasma spraying significantly reduces shrinkage, and cracking while increasing physical properties of the structure over that obtainable by employing previously known powder metallurgical procedures.

Method of preparing a two-way shape memory alloy

Patent Johnson, Alfred D [5383 Bancroft Ave., Oakland, CA 94601]

A two-way shape memory alloy, a method of training a shape memory alloy, and a heat engine employing the two-way shape memory alloy to do external work during both heating and cooling phases. The alloy is heated under a first training stress to a temperature which is above the upper operating temperature of the alloy, then cooled to a cold temperature below the zero-force transition temperature of the alloy, then deformed while applying a second training stress which is greater in magnitude than the stress at which the alloy is to be operated, then heated back to the hot temperature,more »« less

Method to fabricate quantum dot field-effect transistors without bias-stress effect

Patent Law, Matt; Tolentino, Jason

Disclosed herein are embodiments of a method to form quantum dot field-effect transistors (QD FETs) having little to no bias-stress effect. Bias-stress effect can be reduced or eliminated through, as an example, the use of a gas or liquid to remove ligands and/or reduce charge trapping on the QD FETs, followed by deposition of an inorganic or organic matrix around the QDs in the FET.

Method for fabricating uranium foils and uranium alloy foils

Patent Hofman, Gerard L [Downers Grove, IL]; Meyer, Mitchell K [Idaho Falls, ID]; Knighton, Gaven C [Moore, ID]; ...

A method of producing thin foils of uranium or an alloy. The uranium or alloy is cast as a plate or sheet having a thickness less than about 5 mm and thereafter cold rolled in one or more passes at substantially ambient temperatures until the uranium or alloy thereof is in the shape of a foil having a thickness less than about 1.0 mm. The uranium alloy includes one or more of Zr, Nb, Mo, Cr, Fe, Si, Ni, Cu or Al.
