Abstract:
This invention relates to a method for producing a weldable titanium alloy and/or composite wire by cold compaction, extrusion and rolling of a blended mixture of titanium sponge and alloying additions and/or reinforcing particles, where the method comprises the following successive process steps: a) forming a green object by; - blending particulates of titanium sponge with a particle diameter in the range from 0.5 to 10 mm with one or more powdered alloying additions with particle size in the range from 50– 250 μm, -cold compacting the blended mixture and subjecting the blended mixture including lubricant to a pressure in the range from 750 to 1250 MPa, b) forming a work body of alloyed titanium by; - heating the green object in a protected atmosphere up to a temperature in the range from 1000 to 1250 °C and holding the temperature for a period of at least 4 hours, and then - hot working the green object at a temperature of less than 200 °C apart from the beta transition temperature of the titanium alloy and shaping the green object to obtain an elongated profile, and c) forming the welding wire by: - rolling the elongated profile body placing the work body in a rolling mill with one or more rolls placed in series to form the weldable wire with the desired diameter.
Abstract:
A process for producing a weldable titanium or titanium alloy wire characterised in that full consolidation of the wire is achieved via solid-state processing entailing compaction, extrusion, and rolling, whereby melting of the constituent titanium sponge particles does not occur.
Abstract:
This invention describes a method of producing a metal, M 1 , in an electrolytic cell consisting of a molten electrolyte, M z Y - M z O, at least one anode and at least one cathode, characterised in that the passage of current between said anode(s) and cathode(s) through said electrolyte, produces a metal, M 1 , from a raw material, M 1 X, containing a non-metallic species, X, under conditions such that the potential at the cathode causes the reduction of the M z cation and the formation of M 2 at activities less than one, and the potential at the cathode is insufficient to cause formation of M z metal as a discrete solid or liquid phase, and the M z so produced reduces the raw material, M 1 X, at the cathode, to M 1 .
