Definitions
- the present disclosure relates to copper-nickel-tin-manganese alloys.
- Copper alloys used in oil exploration and production must exhibit high impact toughness (e.g., at least 20 ft-lbs).
- toughness refers to the ability of an alloy to absorb energy and plastically deform without fracturing. Therefore, toughness requires a balance of strength and ductility. Alloys may also be exposed to corrosive materials such as hydrogen sulfide (H 2 S) and deleterious conditions such as high bearing wear and friction. Hydrogen sulfide is a colorless gas which exhibits a foul odor like that of rotten eggs. Hydrogen sulfide is heavier than air, extremely poisonous, flammable, and explosive in addition to being highly corrosive. Additionally, aircraft landing systems require high resistance to low velocity, high load sliding bearing forces during takeoffs and landings.
- the present disclosure relates to copper-nickel-tin-manganese alloys.
- the alloys exhibit high impact toughness and good resistance to corrosion, wear, and friction, particularly enhanced by fabrication deformation (cold work).
- an alloy including copper; nickel; tin; and from about 1 .9 to about 20 wt% manganese.
- the nickel is present in an amount of from about 5 to about 25 wt% and/or the tin is present in an amount of from about 5 to about 10 wt%.
- the manganese may be present in an amount of from about 1 .9 to about 10 wt%, including from about 1 .9 to about 5 wt%, from about 1 .9 to about 2 wt%, and from about 2.0 to about 10 wt%.
- an article comprising a copper-nickel-tin- manganese alloy.
- the manganese is present in in the alloy in an amount of from about 1 .9 to about 20 wt%.
- the article may be selected from the group consisting of a bushing, an instrument housing, a connector, a centralizer, a fastener, a drill collar, a mold for plastic shapes, a welding arm, an electrode, and a certified ingot.
- the article is in the shape of a strip, a rod, a bar, a tube, or a plate.
- the alloy may include from about 5 to about 25 wt% nickel and from about 5 to about 10 wt% tin.
- the article has at least one dimension in excess of about 5 inches.
- the article may be an aircraft landing system or a component thereof.
- Disclosed in further embodiments is a method for producing an article.
- the method includes providing a copper-nickel-tin alloy; and adding 0.2 to 20 wt% manganese to the copper-nickel-tin alloy based on the total weight of the article.
- the method further includes cold working the article.
- the nickel is present in an amount of from about 5 to about 25 wt% of the article and/or the tin is present in an amount of from about 5 to about 10 wt% of the article.
- the manganese may be present in an amount of from about 0.2 to about 10 wt%, including from about 0.2 to about 5 wt%, from about 0.2 to about 2 wt%, and from about 0.2 to about 1 .9 wt%.
- FIG. 1 is a flow chart illustrating an exemplary method of the present disclosure.
- a value modified by a term or terms, such as “about” and “substantially,” may not be limited to the precise value specified.
- the approximating language may correspond to the precision of an instrument for measuring the value.
- the modifier “about” should also be considered as disclosing the range defined by the absolute values of the two endpoints. For example, the expression “from about 2 to about 4" also discloses the range “from 2 to 4.”
- spinodal alloy refers to an alloy whose chemical composition is such that it is capable of undergoing spinodal decomposition.
- spinodal alloy refers to alloy chemistry, not physical state. Therefore, a “spinodal alloy” may or may not have undergone spinodal decomposition and may or not be in the process of undergoing spinodal decomposition.
- FIG. 1 illustrates an exemplary method 100 for producing an article.
- the method 100 includes melting a copper-nickel-tin alloy 110; adding 0.2 to 20 wt% manganese to the copper-nickel-tin alloy based on the total weight of the article 120; casting the alloy 125; optionally solution annealing 130; optionally cold working the article 140; and optionally heat treating the article 150.
- the copper-nickel-tin alloy may be a spinodal alloy.
- the preparation of a properly proportioned batch of copper, nickel, and tin is followed by melting 110 the combination.
- the melting 110 may be carried out in a gas- fired, electrical induction or arc furnace of a size matched to the desired solidified product configuration.
- the melting temperatures is at least about 2057 °F with a superheat dependent on the casting process and in the range of 150 to 400°F.
- the addition of manganese 120 may be carried out by dissolving the manganese into the melt at a temperature of at least about 2100 °F and preferably in the range of from about 2200 to about 2350 °F.
- the alloy is cast 125.
- Casting of the alloy may be performed following melt temperature stabilization with appropriate superheat into continuous cast billets or shapes. In addition, casting may also be performed to produce ingots, semi-finished parts, near-net parts, shot, pre-alloyed powder, or other discrete forms.
- some magnesium is added during the melting 110, adding 120, and/or solution annealing 130 in order to reduce the oxygen content of the alloy. Magnesium oxide is formed which can be removed from the alloy mass.
- Strength may also be improved via work hardening (e.g., cold working 140) and/or a spinodal aging treatment. These features improve overall strength-ductility combinations while achieving improvements in other properties such as strength-impact toughness combinations, corrosion resistance, and bearing qualities.
- Cold working is the strengthening of a metal by plastic deformation. This is typically achieved by squeezing, bending, drawing, or shearing the metal at a temperature below its recrystallization temperature.
- the alloy can be hammered, stretched, and otherwise formed. This cold working can increase the hardness, yield strength, and/or tensile strength of the article formed from the alloy.
- the heat-treated spinodal structure retains the same geometry as the original and the articles do not distort during heat treatment as a result of the similar size of the atoms.
- the copper-nickel-tin alloy may be a spinodal alloy.
- Spinodal alloys in most cases, exhibit an anomaly in their phase diagram called a miscibility gap.
- atomic ordering takes place within the existing crystal lattice structure. The resulting two-phase structure is stable at temperatures significantly below the gap.
- Copper-nickel-tin spinodal alloys exhibit a beneficial combination of properties such as high strength, excellent tribological characteristics, and high corrosion resistance in seawater and acid environments.
- An increase in the yield strength of the base metal may result from spinodal decomposition in the copper-nickel-tin alloys.
- Copper alloys have very high electrical and thermal conductivity compared to conventional high-performance ferrous, nickel, and titanium alloys. Conventional copper alloys are seldom used in demanding applications that require a high degree of hardness. However, copper-nickel-tin spinodal alloys combine high hardness and conductivity in both hardened cast and wrought conditions.
- An inert atmosphere e.g., including argon and/or carbondioixide/monoxide
- protective covers e.g., vermiculite, alumina, and/or graphite
- Reactive metals such as magnesium, calcium, beryllium, and/or tungsten may be added after initial meltdown to ensure low concentrations of dissolved oxygen.
- Casting may be performed following melt temperature stabilization with appropriate superheat into continuous cast billets, parts, or shot.
- solution annealing 130 is carried out for from about 1 to about 12 hours at a temperature of from about 1350 to about 1625 °F.
- Cold working 140 refers to mechanically deforming a metal at a temperature below the recrystallization temperature.
- the metal becomes more difficult to deform as the amount of deformation increases.
- the material is work hardened or strain hardened. This step is optional.
- the metal may be further strengthened by heat treating 150.
- the heat treating includes reheating in a temperature range of from about 600 to about 950 °F for from about 1 to about 8 hours to effect hardening.
- the nickel may be present in an amount of from about 5 to about 25 wt%, including from about 10 to about 20 wt% and about 15 wt%. In more specific embodiments, the nickel is present in amounts of about 8 wt% to about 16 wt%, about 14 wt% to about 16 wt%, about 8 wt% to about 10 wt%, or about 10 wt% to about 12 wt%.
- the tin may be present in an amount of from about 5 to about 10 wt%, including from about 6 to about 9 wt% and from about 7 to about 8 wt%. In more specific embodiments, the tin is present in amounts of about 5 wt% to about 9 wt%, or about 7 wt% to about 9 wt%, or about 5 wt% to about 7 wt%.
- the manganese may be added in an amount of at least about 0.2 wt%, including at least about 0.5 wt%, at least about 1 wt%, and at least about 1 .5 wt%. In more specific embodiments, the manganese is present in amounts of at least 4 wt%, at least 5 wt%, about 4 wt% to about 12 wt%, about 5 wt% to about 21 wt%, about 16 wt% to about 21 wt%, or about 19 wt% to about 21 wt%.
