A process for producing a copper-beryllium alloy product. The process comprises preparing a base alloy having 0.15 wt %-4.0 wt % beryllium and having grains and an initial cross section area. The process further comprises cold working the base alloy to a percentage of cold reduction of area (CRA) greater than 40%, based on the initial cross section area, and heat treating the cold worked alloy to produce the copper-beryllium alloy product. The grain structure of the copper-beryllium alloy product has an orientation angle of less than 45° when viewed along the direction of the cold working. The copper-beryllium alloy product demonstrates a fatigue strength of at least 385 MPa after 10cycles of testing.

Copper-beryllium alloy with high strength

Methods for producing a coiled strip of metal matrix composite (MMC) material are disclosed. The methods include a combination of hot rolling and warm rolling processes that reduce the thickness of the input material and increase its ductility. The resulting MMC strip can be coiled, which is useful for high volume coil-to-coil applications.

A process of synthesizing a yttrium aluminum garnet (YAG) powder. The process comprises introducing powders of yttria and silica to form a powder mixture, wherein alumina is not added to the powder mixture. Milling the powder mixture in the presence of an alumina grinding media and a solvent forms a powder slurry. Processing the powder slurry forms a green compact. Calcining the green compact at a temperature of from 1100&#xb0; C. to 1650&#xb0; C. for greater than 8 hours in air to 50% or less theoretical density forms a YAG compact of at least 92 wt % YAlO. Milling the YAG compact, without a grinding media, and drying produces the YAG powder. Processes further include introducing a dopant to the powder mixture to produce doped YAG powder.

Yttrium aluminum garnet powder and processes for synthesizing same

A cold worked and spinodally-hardened copper alloy comprising from about 8 to about 20 wt % nickel, and from about 5 to about 11 wt % tin, the remaining balance being copper, and having a 0.2% offset yield strength of at least 75 ksi, is used to form a sucker rod coupling or subcoupling. Each coupling is formed from a core having two ends, each end having an internal thread. These box ends engage the pin of a sucker rod or other rod. The exterior surface of the core includes grooves running between the two ends.

Coupling for rods

A spinodal copper-nickel-tin alloy with a combination of improved impact strength, yield strength, and ductility is disclosed. The alloy is formed by process treatment steps including solution annealing, cold working and spinodal hardening. These include such processes as a first heat treatment/homogenization step followed by hot working, solution annealing, cold working, and a second heat treatment/spinodally hardening step. The spinodal alloys so produced are useful for applications demanding enhanced strength and ductility such as for pipes and tubes used in the oil and gas industry.

Copper-nickel-tin alloy with high toughness

A sucker rod string is formed from sucker rods and sucker rod couplings. The sucker rod couplings are formed from a spinodally-hardened copper alloy comprising from about 8 to about 20 wt % nickel, and from about 5 to about 11 wt % tin, the remaining balance being copper, and having a sliding coefficient of friction of 0.4 or less when measured against carbon steel. The sucker rod string has low friction and improved pumping stroke, enhanced pumping capacity, and less load in the overall system.

Low friction and high wear resistant sucker rod string

Disclosed are various processes for preparing a strip or plate of a copper-nickel-tin alloy. The processes begin with an input, usually of a rectangular shape. The input is hot rolled and annealed. The input is then subjected to a first cold reduction, a first annealing a second cold reduction, a second annealing, a third cold reduction, and a third annealing. If desired, a fourth cold reduction, a fourth annealing, and a fifth cold reduction may be performed. The resulting strip or plate is very smooth and has increased fatigue life, along with high strength.

Copper-nickel-tin alloys

A sucker rod guide having low friction and high wear resistance is disclosed herein, along with a fluid extraction system comprising the same. At least a part of the exterior surface of the sucker rod guide is formed from a cold worked and spinodally-hardenable or spinodally-hardened copper alloy comprising from about 5 to about 20 wt % nickel, and from about 5 to about 10 wt % tin, the remaining balance being copper, and having a 0.2% offset yield strength of at least 75 ksi. The guide includes a smoothbore adapted to surround and engage the surface of a sucker rod. The exterior surface of the guide can include grooves miming between the two ends. In particular embodiments, the guide is made by joining together two identical guide segments. In other embodiments, the guide is a single integral piece molded around a sucker rod.

The present disclosure relates to a method of applying a wear-resistant copper-nickel-tin coating to a substrate using a thermal spray process. Briefly, a copper-nickel-tin alloy feedstock is converted into a powder or droplet form, then sprayed onto a substrate to form a coating thereon.
