Detailed Description Of The Invention
The disclosure relates to iron-nickel (Fe-Ni) base alloy.Think, the example table of Fe-Ni disclosed herein reveals hot hardness, hot strength, fatigue strength and antiwear characteristic.These characteristics make this alloy can be used for high temperature application, comprise such as cylinder head, intake valve, vent valve and exhaust-gas-recirculation valve.Other application of this alloy wherein can be used to comprise the shield cap of such as turbine applications, fastening piece, after-burner (afterburner) parts, combustion chamber components, exhaust system oxygen sensors and be exposed to other parts of the temperature of raising, waste gas and condensate environments.
The example of Fe-Ni disclosed herein achieves high-temperature mechanical property by precipitation hardening and sosoloid strengthening.This Fe-Ni is developed by heat treatment step, and described heat treatment step can comprise solution-treated to dissolve strengthening composition, is then aging thermal treatment to carry out precipitated phase with the form producing the mechanical properties desired by this alloy desired use and distribution.
In disclosed alloy, finely divided, stable and orderly intermetallic phase (Fe, Ni)
3the precipitation of (Al, Ti, Nb) (being commonly referred to the crystalline structure of gammaprime (γ ')) contributes to the hot strength of this alloy.In addition, the carbon at least partially in alloy forms primary carbide (primarycarbides, such as TiC and/or NbC) to strengthen wear resistance.It being understood that these carbide may precipitate in the alloy at random.
The example of alloy disclosed herein at least comprises C, Ni, Cr, Ti, Al, Nb (Ta), Mg and Fe.As used herein, Nb (Ta) refers to niobium, and it can along with a small amount of tantalum.Nb usually along with the Ta as pollutent or inevitable impurity because these two kinds of elements are difficult to be separated.Symbol Nb (Ta) admits that the niobium recorded may comprise a small amount of tantalum.Furthermore, it is noted that although Ta with Nb performance is in the alloy similar, Ta is heavier, be therefore not so good as Nb under identical weight so effective.
It being understood that ought not providing the lower of scope prescribes a time limit (such as " element of maximum X % by weight "), this lower limit is 0 % by weight, may not there is this element-specific thus in alloy.But when describing a kind of element and " existing with the amount of maximum X % by weight ", this lower limit is greater than 0 % by weight, there is this element of at least some in the alloy.
In some cases, element-specific may and involuntaryly to join in alloy, but may to be equivalent to a small amount of existence of inevitable impurity.Such as, P, S, Mn, Si, W, Mo and Cu are the examples of the inevitable usual impurities deliberately not adding in alloy but still exist.
The example of disclosed alloy is containing the magnesium be improved (Mg) or Mg and calcium (Ca) content (compared with other superalloy), and it contributes to the grain refining that this alloy has improvement.Think, add Mg or Mg and Ca with amount disclosed herein, to grain refining, there is desired effect.Also think, the combination adding magnesium or magnesium and calcium in alloy disclosed herein advantageously improves the die life in forging process.In an example, 15% can be improved die life.
Magnesium is present in alloy with maximum amount of 0.030 % by weight.Magnesium can also exist with less amount, and such as maximum 0.020 % by weight or maximum 0.010 % by weight.As an example, magnesium with 0.010 % by weight to 0.020 % by weight, or can exist with 0.020 % by weight to 0.030 % by weight.As previously mentioned, think, magnesium contributes at least improving grain refining and die life.In addition, can add Mg, (such as C, Ni, Cr, Ti, Al, Nb (Ta) and Fe) to remain unchanged, this improves grain refining when not affecting the balancing each other of alloy to other element of simultaneously alloy.
In some instances, calcium is joined in alloy, in other example, do not comprise calcium in the alloy.When it is present, calcium can comprise in the alloy with maximum maximum of 0.020 % by weight.Maximum can also be lower, and such as maximum 0.015 % by weight or maximum 0.010 % by weight.Think that (as mentioned above) calcium also contributes to improving grain refining.
Carbon can be present in alloy with the amount of 0.15 % by weight to 0.30 % by weight.Alloy can also containing carbon more among a small circle, and the example comprises 0.16 % by weight to 0.30 % by weight, and 0.15 % by weight to 0.25 % by weight, 0.15 % by weight to 0.20 % by weight, or 0.15 % by weight to about 0.17 % by weight.As mentioned above, carbon is combined with niobium (i.e. Nb (Ta)) and titanium and forms primary carbide crystal grain at least partially.The formation of primary carbide can occur in Casting Ingot Solidification Process.Usually, when the per-cent of carbon declines, the per-cent of primary carbide also will so.Carbide grain positively affects binding property and the wear resistance of alloy.
Nickel can be present in alloy with the amount of 30.25 % by weight to 35 % by weight.Alloy can also containing nickel more among a small circle, and the example comprises 30.25 % by weight to 34.50 % by weight, and 31.0 % by weight to 35.0 % by weight, 32.0 % by weight to 35.0 % by weight, 33.0 % by weight to 35.0 % by weight, or 34.0 % by weight to 35.0 % by weight.Nickel and iron are mutually solvable.Can add nickel with stable austenite matrix (γ) promotes to form γ ' phase/crystalline structure, which improves the hot strength of alloy.Nickel can also promote to form gammadoubleprime (γ ") crystalline structure (i.e. Ni
3nb), it also contributes to the hot strength of alloy.Nickel can also with titanium with Ni
3ti form forms crisp Eta (η) phase.Balance aluminium (Al), titanium (Ti) and niobium (Nb (Ta)) carefully will prevent from forming Eta phase η with nickel (Ni).
In addition, think, in embodiment disclosed herein relatively low amounts and the narrow range of carbon and the relative high of Nb (Ta) amount (with other known alloy phase than) improve γ ' and/or γ " phase, and the intensity which thereby enhancing alloy disclosed herein.
In some examples of alloy, cobalt also can substitute nickel at least partially.Cobalt can substitute the nickel (causing the creep strength improved) in γ phase, and this allows more nickel to form γ ' phase.
Chromium can be present in alloy with the amount of 15.0 % by weight to 17.0 % by weight.Chromium provides sosoloid to strengthen to alloy substrate, and is also formed for strong (tenacious) oxide compound of the clinging power of oxidation-resistance.The oxide compound that this clinging power is strong is considered to the surface being present in alloy, and it advantageously inhibits high temperature oxidation to be formed and corrosion and wear rate and rate of oxidation are minimized.Exceed 20 % by weight chromium existed and form sigma (σ) or alphaprime (α ') phase, this can precipitate at exhaust work temperature.This precipitation can hinder the wear resistance of alloy, and therefore chromium exists with the amount in the given range of 15.0 % by weight to 17.0 % by weight.
Aluminium can be present in alloy with the amount of 1.60 % by weight to 2.50 % by weight.Alloy can also containing aluminium more among a small circle, and the example is 1.65 % by weight to 2.30 % by weight, and 1.60 % by weight to 2.20 % by weight, 1.60 % by weight to 2.00 % by weight, or 1.60 % by weight to 1.80 % by weight.Aluminium is combined with nickel to precipitate γ ' phase, can be considered as the principal component of γ ' crystalline structure thus.In addition, aluminium provides oxidant protection under high temperature to a certain degree.It may be unacceptable that the amount had been found that outside the scope that provides herein adds aluminium.Such as, when to add aluminium lower than the amount of 1.60 % by weight, the instability of γ ' phase transformation, may be converted into η [(Fe, Ni)
3(Ti, Al)] phase, this can fall low-alloyed mechanical properties.In addition, to add higher than the amount of 3 % by weight hot workability that aluminium can weaken alloy.In addition, the γ ' containing high-content aluminium has the lattice strain mismatch with γ matrix hardly, and increases strengthening ability hardly thus.Therefore, desirably comprise aluminium with the amount provided herein.
Titanium can be present in alloy with the amount of 1.60 % by weight to 3.20 % by weight.Alloy can also containing titanium more among a small circle, and the example comprises 2.40 % by weight to 3.20 % by weight, and 2.20 % by weight to 2.60 % by weight, 1.90 % by weight to 2.30 % by weight, or 1.60 % by weight to 1.80 % by weight.Think, add the lattice strain mismatch that titanium can improve aluminium and γ matrix.Titanium also improves the Apb Energies of γ ' crystalline structure.If titanium is to exist lower than 1.5 % by weight, then the solution temperature of γ ' phase is considered to reduce.In addition, higher than 1.5 titanium/aluminum ratio or too high titanium content can η phase be caused to grow/precipitate at higher than the temperature of 700 DEG C.On the contrary, if titanium/aluminum ratio is lower than 1.0, alloy has slow age hardening response.As mentioned above, titanium is also combined with carbon and precipitates primary carbide at least partially, and it contributes to wear resistance.
Niobium (i.e. Nb (Ta)) can be present in alloy with the amount of 2.10 % by weight to 3.20 % by weight.Alloy can containing Nb (Ta) more among a small circle, the example comprises 2.10 % by weight to 2.40 % by weight, 2.40 % by weight to 2.80 % by weight, 2.60 % by weight to 3.00 % by weight, 2.80 % by weight to 3.20 % by weight, or 2.90 % by weight to 3.00 % by weight, in some cases, desirably use the Nb (Ta) of even more a large amount.As mentioned above, niobium (when using with amount disclosed herein) contributes to forming γ ' phase and/or γ " phase.As mentioned above, two kinds of structures all contribute to intensity.Niobium also contributes to improving γ ' and γ, and " force of cohesion (coherency) between crystalline structure, restriction γ ' grain coarsening, improves weldability, and improves resistance to sulfuration corrodibility.Except forming γ ' phase, niobium also forms primary carbide, this provides wear resistance.
In this article in disclosed example, alloy comprises carbide forming element Nb (Ta) and the Ti of minimum.This minimum can be desirable to make all carbon react form carbide, and has enough Nb (Ta) and/or Ti to form γ ' phase and/or γ " phase.In an example, the total amount (i.e. Nb (Ta)+Ti) of niobium and titanium is more than or equal to 4.40 % by weight.In another example, the amount that Nb (Ta) adds Ti is more than or equal to 4.50 % by weight, and in a further example, the amount that Nb (Ta) adds Ti is more than or equal to 4.60 % by weight.
Alloy can also comprise maximum copper of 0.50 % by weight.Alloy less maximum can also contain copper, and the example comprises maximum 0.35 % by weight, 0.25 % by weight, 0.15 % by weight or be even low to moderate maximum 0.010 % by weight.Copper may be of value to resistance to sulfuration corrodibility.But, if there is too many copper, may oxidant protection under high temperature be hindered in some cases.Some examples of alloy also do not comprise copper.
Alloy can also comprise molybdenum, tungsten and/or manganese.Maximum molybdenum of 0.25 % by weight and tungsten separately can be there is in the alloy.In some instances, the maximum of molybdenum can be maximum 0.20 % by weight, 0.15 % by weight, 0.10 % by weight or 0.010 % by weight.In some instances, the maximum of tungsten can be maximum 0.15 % by weight, 0.10 % by weight or 0.002 % by weight.Using less amount (no matter deliberately add or comprise as inevitable impurity), molybdenum and tungsten all can provide sosoloid to strengthen to alloy substrate, and can provide the tolerance to creep when alloy is exposed to high temperature.Maximum manganese of 0.50 % by weight can be comprised in the alloy.Manganese provides sosoloid to strengthen to matrix, and also contributes to melt deoxidation.Excessive these elements any may be unacceptable, because they stablize ferrite (ferrite).
Some examples of alloy can comprise boron, zirconium or its combination.When comprising, these elements can be present in alloy with maximum amount of 0.015 % by weight separately.Boron, zirconium or its combination can exist with less scope, as 0.005 % by weight to 0.015 % by weight, or 0.010 % by weight to 0.015 % by weight.Boron and/or zirconium contribute to strengthening crystal boundary and improve creep.In some cases, zirconium may be more desirable than boron, because think that boron can be mixed into γ ' phase.But, if use boron or zirconium with higher amount, may incipient melting be there is.
In some instances, also may exist in the alloy nonmetal.As mentioned above, the inevitable impurity of some nonmetal conducts exists.In an example, maximum phosphorus of 0.01 % by weight or 0.02 % by weight may reside in alloy; Maximum sulphur of 0.001 % by weight, 0.005 % by weight, 0.010 % by weight or 0.015 % by weight may reside in alloy; And/or maximum silicon of 0.10 % by weight or 0.50 % by weight may reside in alloy.
Some other metals, as hafnium, it has the chemical property similar with titanium, can be mixed into γ ' crystalline structure.When comprising, this amount is maximum 0.2 % by weight.
In this article in disclosed any embodiment, the surplus of alloy is iron, separately or with accidentally/inevitably together with impurity.Inevitable impurity can comprise those that discussed, and the oxygen of trace and nitrogen, because their may be uncontrollable.
Alloy disclosed herein can use ordinary method to prepare.Element material can pass through vacuum induction, air induction melting, arc melting or argon oxygen decarburization, esr (ESR) or its combination and carry out melting.In an example, air-melted technology is adopted.Melting material is cast into ingot casting subsequently, and it is exposed to immersion treatment subsequently.Ingot casting can cleaned (scarfed) impose forging and rolling to form bar.
