A method may include annealing a material including iron and nitrogen in the presence of an applied magnetic field to form at least one FeNphase domain. The applied magnetic field may have a strength of at least about 0.2 Tesla (T).

Applied magnetic field synthesis and processing of iron nitride magnetic materials

The invention provides a component formed of an aluminum alloy for use in a vehicle, for example an automotive vehicle component requiring high strength, light-weight, and a complex three-dimensional shape, and a method of manufacturing the component. The method begins by providing a blank formed of an aluminum alloy which is already solution heat treated and tempered, and thus has a temper designation of about T4. The method further includes heating the blank to a temperature of 150° C. to 350° C., preferably 190° C. to 225° C. The method next includes quickly transferring the blank to a hot or warm forming apparatus, and stamping the blank to form the complex three-dimensional shape. Immediately after the forming step, the component has a temper designation of about T6, but preferably not greater than T6, and thus is ready for use in the vehicle without any post heat treatment or machining.

High strength aluminum stamping

Methods for forming a metal oxide electrolyte include applying a metal compound to a first material in powder form thereby forming a slurry, applying the slurry to an electrode, and converting at least some of the metal compound to form a metal oxide, thereby forming the metal oxide electrolyte on the electrode. Unexpectedly, the metal oxide electrolyte may have an ionic conductivity greater than the bulk ionic conductivity of the first material and of the metal oxide, possibly because of the nature of the interface between the first material and the metal oxide.

Low temperature electrolytes for solid oxide cells having high ionic conductivity

A system and method for an improved material flow through an extrusion machine by altering the material properties in a magnetic field are provided. The electromagnetic extrusion system includes a ram that is moved into a chamber containing an extrusion material to force the extrusion material out of an opening defined, at least in part, by a die to create an extrusion with a cross-sectional shape corresponding to the predetermined shape of the opening. An electromagnetic winding of electrically conductive material is embedded within a tool retainer block surrounding the container and is helically wound about the chamber and carries a DC electrical current to generate a magnetic field having a magnetic flux density of at least 2 Tesla within the extrusion material to dissipate dislocation defect structures in the extrusion material being extruded via the magnetoplasticity effect. The magnetic field therefore provides for reduced flow stress on the tooling.

Electromagnetic extrusion

Disclosed herein is a method comprising disposing a container containing a metal and/or ferromagnetic solid and abrasive particles in a static magnetic field; where the container is surrounded by an induction coil; activating the induction coil with an electrical current, to heat up the metallic or ferromagnetic solid to form a fluid; generating sonic energy to produce acoustic cavitation and abrasion between the abrasive particles and the container; and producing nanoparticles that comprise elements from the container, the metal and/or the ferromagnetic solid and the abrasive particles. Disclosed herein too is a composition comprising first metal or a first ceramic; and particles comprising carbides and/or nitrides dispersed therein. Disclosed herein too is a composition comprising nanoparticles comprising chromium carbide, iron carbide, nickel carbide, &#x3b3;-Fe and magnesium nitride.

Method for producing nanoparticles and the nanoparticles produced therefrom

Methods for forming a metal oxide electrolyte improve ionic conductivity. Some of those methods involve applying a first metal compound to a substrate, converting that metal compound to a metal oxide, applying a different metal compound to the metal oxide, and converting the different metal compound to form a second metal oxide. That substrate may be in nanobar form that conforms to an orientation imparted by a magnetic field or an electric field applied before or during the converting. Electrolytes so formed can be used in solid oxide fuel cells, electrolyzers, and sensors, among other applications.

An example apparatus can comprise an emitter to emit radio frequency radiation, an absorber that changes temperature based on emissions from the emitter, and one or more sensors to measure a temperature difference between a sample and a reference coupled to the absorber.

An advanced blowout preventer that includes an arrester section and a shear section. The arrester section includes a number or arrester rings that are shaped to extend downwardly. The shape of the arrester rings allows the force of gas flowing out of the well to assist in closing the rings. The arrester section may have a number of arrester rings that cooperate to significantly reduce fluid from flowing in the annulus between a section of drill pipe and the blowout preventer. The advanced blowout preventer may also include a shear section. The shear section is configured to engage and shear a section of pipe using induction.

A method of thermomagnetically processing an aluminum alloy entails heat treating an aluminum alloy, and applying a high field strength magnetic field of at least about 2 Tesla to the aluminum alloy during the heat treating. The heat treating and the application of the high field strength magnetic field are carried out for a treatment time sufficient to achieve a predetermined standard strength of the aluminum alloy, and the treatment time is reduced by at least about 50% compared to heat treating the aluminum alloy without the magnetic field.
