Apparatuses, systems, and methods for manufacturing grooved wire are provided. A set of rollers may form grooves on an outermost surface of a wire along an axial distance of the wire. The set of rollers may include a first roller and a second roller. The first and second roller may include groove-fabricating portions aligned circumferentially around a radial face of each of the rollers. The first roller and second roller, via the groove-fabricating portions, may form grooves on the outermost surface of the wire along the axial direction of the wire.

A method of producing a clad billet includes heating a corrosion resistant alloy (CRA) cylinder having a hollow interior to expand its inner diameter; inserting a solid carbon or low-alloy steel (CS) material into the hollow interior of the heated (CRA) cylinder so that an outer surface of the (CS) material faces the inner diameter of the (CRA) cylinder; cooling the (CRA) cylinder to contract and shrink the inner diameter of the (CRA) cylinder onto the outer surface of the (CS) material creating an interference fit at an interface with the outer surface, resulting in a composite billet assembly; and hot extruding the composite billet assembly to reduce its size and form the clad billet having a metallurgical bond between the (CS) material and the (CRA) cylinder. The clad billet can be hot-rolled to form metallurgically-bonded clad bar, or can be cold pilgered/cold drawn to form a metallurgically-bonded clad pipe.

Provided is a medical wire including: a main wire-strand portion that is formed of a plurality of main wire strands and that extends over the entire length of the medical wire; and at least one sub wire-strand portion that is disposed at an outer circumference of the main wire-strand portion, that is secured to the main wire-strand portion, and that is formed of a sub wire strand, wherein the diameter of the sub wire strand is at least twice the diameter of the main wire strand, and a first region having a relatively small lateral cross-sectional area and a second region having a lateral cross-sectional area that is greater than that of the first region are included.

A metallic part is disclosed. The part may comprise a functionally graded monolithic structure characterized by a variation between a first material composition of a first structural element and a second material composition of at least one of a second structural element. The first material composition may comprise an alpha-beta titanium alloy. The second material composition may comprise a beta titanium alloy.

A method of making a matrix material with particular mechanical and/or physical properties, including providing a mixture of micro and/or nano particle and a cored wire as a feed stock, and physically incorporating the micro and/or nano particles into the cored wire to thereby produce the matrix material. Such method could also include the physical incorporation of the micro and/or nano particles into the cored wire being accomplished using a continuous forming process to thoroughly mix the micro and/or nano particles to thereby produce a dispersion mixture of particles and/or a drawing process through successive dies to process the matrix material. An elongated material is also disclosed, having an exterior portion including a matrix material and a core material generally surrounded by the exterior portion and having particles including one or more micro particles, nano particles, macro or nano matrix material particles and/or a second matrix material.

The invention relates to an electrical transportation wire made of aluminum alloy comprising aluminum, zirconium and unavoidable impurities, characterized in that said alloy comprises at least 80 parts by weight of zirconium in the form of precipitates (Al.sub.3Zr) per 100 parts by weight of zirconium in said aluminum alloy.

A method of titanium wire additive manufacturing is disclosed. The method may comprise mixing a plurality of powdered metals comprising titanium, iron, vanadium, and aluminum to produce a powder blend, sintering the powder blend to form a billet, performing a wire forming operation to produce a worked wire, heat treating the worked wire to produce a heat treaded wire, loading the heat treated wire into a wirefeed additive manufacturing machine, and producing a metallic component from the heat treated wire. The titanium may be a titanium hydride powder.

There is provided a training system capable of performing work. The system has a shape memory alloy (SMA) actuator exhibiting a generally planar transformational behavior. The system further has one or more heating elements for transforming the SMA actuator from an original shape to a trained shape, thereby performing work.

Cables including conductors formed form ultra-conductive copper wires which have a lower temperature coefficient of resistance are disclosed. Methods of making the cables including conductors with ultra-conductive copper wires are further disclosed.

A process for producing an ornamental element, in particular an ornamental chain, comprising the following steps: arranging a tubular polymer core inside a tubular metal casing to form a layered tubular profile; cutting and bending the layered tubular profile to form a plurality of shaped chain links; connecting the chain links to form the ornamental chain.
