Systems, methods, and apparatus to heat welding wire for low hydrogen welding are disclosed. An example method includes drawing a supply material through a die to form a wire; and applying electrical current to a portion of the wire to reduce a hydrogen content of the wire.

Provided is a gadolinium wire rod including gadolinium as a main component and having a Vickers hardness (HV) 120 or less.

Provided is a metal-covered gadolinium wire rod including: a gadolinium wire including gadolinium as a main component, as a core; and a clad layer including, as a main component, a metal other than gadolinium, the clad layer covering the periphery of the core.

A tendon processing system includes at least one tub for supporting a tendon, and an indexing assembly for moving the tub to and between a plurality of processing locations. Each processing location is associated with at least one respective processing device.

An additive manufacturing apparatus to build a three-dimensional metal object using a semi-solid filament extrusion method is disclosed. A frame comprises a carriage capable of moving in Y-axis and Z-axis direction. The frame further comprises an extruder head, which is attached to a support section of the carriage is configured to move in X-axis direction to continuously print a filament in a layer by layer fashion using a thixo-extrusion process on a print bed in a pre-defined three-dimensional path. The filament is a treated metal alloy fed into the extruder head via a feeder mechanism and heated to a semi-solid state to allow the controlled flow of the slurry via a nozzle section to build the three-dimensional extruded object with the predetermined microstructure. The metal alloy is pre-processed using a heat treatment and a mechanical deformation technique to enhance the properties of the filament used in the semi-solid extrusion process.

A method for producing a feedstock wire is produced from a first metal strip and at least one further metal strip by roll forming, wherein in particular the first metal strip and the at least one further metal strip are made of differing metals, preferably of differing meals having differing yield points, wherein a jacket, which in the final shape completely surrounds the at least one further metal strip in the circumferential direction, is formed from the first metal strip in a plurality of passes by roll forming using a plurality of roll stands, and wherein, first, exclusively only the first metal strip is formed to a preliminary shape in a plurality of passes using a first group of roll stands and, thereafter, the first metal strip and the at least one further metal strip are jointly formed to the final shape in a second group of roll stands.

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.

Rods with the transverse cross-section surface area of at least 150 mm.sup.2 and tensile strength UTS above 1200 Mpa is produced using a plastic deformation that consisted of one-pass hydrostatic extrusion of the billet 1 made of austenitic steel, with the initial temperature of the billet being below 100 C. The reduction R of the transverse cross-section surface area of the biller (1), which takes place during the extrusion, is at least 2.

The present disclosure relates to a method for producing a rod-shaped element. In order to provide a method with which it is possible to produce a rod-shaped element which overcomes at least one of the disadvantages of the rod-shaped elements known from the state of the art, it is proposed according to the invention that the method has the steps of providing a tube made of a metal, wherein the tube has a longitudinal direction, providing at least one strand with a plurality of threads, wherein at least one of the threads has carbon fibres, introducing the at least one strand into the tube, with the result that the at least one strand extends in the longitudinal direction in the tube, and cold forming the tube, together with the at least one strand, using a forming tool, with the result that an outside diameter of the tube before the cold forming is larger than the outside diameter of the tube after the cold forming.

A radiopaque composite wire for medical applications comprises a core comprising a rare earth metal, an outer layer comprising a nickel-titanium alloy disposed over the core, and a diffusion barrier comprising a barrier material between the core and the outer layer. A method of making a radiopaque composite wire includes cold drawing a composite billet through a die, where the composite billet includes a tube comprising a nickel-titanium alloy disposed about a rod comprising a rare earth metal, and a barrier layer comprising a barrier material disposed between the tube and the rod. After cold drawing, the composite billet is annealed to relieve strain. After multiple passes of the cold drawing and annealing, a radiopaque composite wire having a core comprising the rare earth metal, an outer layer comprising the nickel-titanium alloy, and a diffusion barrier comprising the barrier material between the core and the outer layer is formed.
