Description

The application in relevant this alloy of nickel-base alloy, member, gas turbine installation and palladium
Invention field
The present invention relates to have the nickel-base alloy that is used for the pyritous excellent specific property.Alloy of the present invention for example can be used for the member of internal combustion turbine.The invention still further relates to the member of making by alloy of the present invention.Moreover, the invention still further relates to gas turbine installation.In addition, the invention still further relates to the application of Pd in alloy.
Background technology
Known have a multiple alloy that high temperature is used that is suitable for.This class alloy is called superalloy.Term " superalloy " be representative based on as nickel, iron and cobalt and contain the complex alloys of interpolation element such as chromium, carbon, aluminium, tungsten, rhenium, titanium, silicon and molybdenum.Term "based" means the element of the maximum weight part of alloy, and its weight % that does not promptly have other in alloy is equal to or higher than the element of the weight % of infrastructure elements.This interpolation element is generally used for giving high values of mechanical strength and the creep resistance under the high temperature, and improves scale resistance and heat/corrosion resistance.To nickel base superalloy, its high-heat strength part is obtained by precipitation hardening by the solid solution hardening of using element such as tungsten or molybdenum and part.This throw out is usually by adding aluminium and titanium to form based on Ni in main material (γ) 3(Ti, intermetallic compound γ ' Al) (" gammaprime ") and making.
File US 6177046 B1 have described γ/γ ' superalloy of a kind of Pd of containing.Adding Pd by this document is for providing improved weldability to this alloy.This document has been listed the very wide content range of alloying element.Gui Ding Pd content is 4-32 weight % in the claims.Press the most preferred alloying element scope of the different embodiment in this document, Pd content should be 5-40 weight % (table 7), 5-45 weight % (table 8) or 8-27 weight % (tables on 17 hurdles).In the specific embodiment of this document, Pd content is very high.The Ni content of suggestion in existing Ni base superalloy up near half should replace (seeing row 9) by Pd.
File US 6007645 describes γ/γ ' nickel base superalloy.The alloy that this document is described has good heat/corrosion resistance, high creep-breaking tenacity and good microstructural stability.This document emphasizes that Cr content should be low.This document has proposed several different alloy composites.Cr content is never greater than 2.9 weight %.File mentions, together with other alloying element, alloy can contain 0-10 weight % one or more be selected from the element of Ru, Rh, Pd, Os, Ir and Pt.And mention that these elements help improving creep-breaking tenacity and scale resistance and erosion resistance.As if this document do not mention the specific embodiment that contains Pd in alloy.
By Liu Yang and Rex B.McLellan at Journal of Materials Research, Vol.11, No.4, in April 1996, " palladium is at the adulterated Ni of B-for the article in the 862-864 page or leaf 3Effect in the hydrogen embrittlement of Al (Effect of palladium on the hydrogen embrittlement of B-doped Ni 3Al) " discussed by adding Pd and can reduce boron-adulterated Ni 3The hydrogen embrittlement of Al.
Known hydrogen can diffuse into alloy, and becomes the reason of the unfavorable characteristic of this alloy thus.For example hydrogen can reduce the ductibility of material, and may be crack reason and make material hardens and crisp.The most important mechanism of these effects is relevant with the reduction of crystal boundary and granule boundary.Also may there be possible disadvantageous synergistic effect in this between H and S, so that forms hydrogen sulfide at crystal boundary and granule boundary.Also known, S helps segregation rather than helps crystal boundary.Even low-down S content also is enough at this crystal boundary place formation hydrogen sulfide layer.When no S, also can produce this problem because of forming nickelous cyanide.Described this class problem can be described as hydrogen embrittlement (HE).
HE can cause because of the existence of hydrogen, but also can take place under wet condition.Alloying element such as Al can consequently form free hydrogen in water oxygenization, referring to early stage mentioned Yang ﹠amp; The article on Scripta Materialia48 (2003) " Environment effects on tensile and low cycle fatiquebehaviour of single crystal nickel base superalloys " of McLellan about people such as the article of γ ' (" gamma prime ") alloy and Nazmy.This hydrogen can diffuse in the alloy and cause HE.
Known Ni base γ/γ ' alloy has excellent high temperature application characteristic, as is used for the member of internal combustion turbine.But reported that also this alloy also has the HE phenomenon, referring to people's such as above mentioned Nazmy article.
Ni base γ/γ ' alloy is very complicated alloy.These alloys have the matrix of γ phase, and this γ is the sosoloid of Ni and other element such as Cr, Co, Fe, W, Mo and Re mutually.In addition, this alloy also contains γ ' phase particle, and this γ ' phase is Ni normally 3The sosoloid of Al and other element such as Ti, Ta and Nb.In addition, this alloy also contains other element, for example for strengthening crystal boundary and/or stable protective oxide layer.Also can mention, different alloying elements often with different concns be present in γ and γ ' mutually in, promptly certain element be easy to attracted to these phases certain mutually in so that the concentration of this element this be higher than in mutually another mutually in.For example once the report, Al often preferred allocation to γ ' mutually in.Also once the newspaper go back, Pd often preferred allocation to γ ' mutually in.In addition, a kind of element is γ and γ ' being distributed in the presence of other element and can having changed in mutually.Notice, add Pd and can produce and make Al be easy to preferred allocation to the effect of γ in mutually.
Summary of the invention
Ni base γ/γ ' alloy components has the protective oxide layer that can prevent hydrogen embrittlement usually.But the inventor notices; also stand the moisture condition if particularly stand as the member of the variation between envrionment temperature and elevated operating temperature and particularly these members; the microstructure of this oxide scales is time to time change, so that this protective oxide layer can unclamp its part provide protection at least or stands mechanical effect and damage its mother metal.The inventor finds, this member is easy to take place hydrogen embrittlement.Because normal air contains a certain amount of humidity, moisture may be a problem in many cases.In addition, the inventor also finds, for example use " wet technology " as the internal combustion turbine of spraying and steam cooling in this hydrogen embrittlement may be a problem.Hydrogen embrittlement can shorten the spendable time of member.For example because internal combustion turbine is expensive device, importantly the member in this class device can move for a long time.
The purpose of this invention is to provide a kind of improved Ni base γ/γ ' alloy, it is applicable to and stands the pyritous member.Therefore special purpose is to provide a kind of alloy with improved soundness and ability hydrogen embrittlement.Particularly the member made from this alloy is in the risk that stands should reduce its hydrogen embrittlement when the small part circulation is the thermal cycling of wet condition.Therefore the purpose of this invention is to provide a kind of alloy that is used for the member that can not damage in long-time running.Another object of the present invention is to provide a kind of member of the member with excellent specific property, particularly anti-hydrogen embrittlement.A purpose provides a kind of gas turbine installation again, and it comprises one or more members that excellent specific property is arranged when high temperature is used.A purpose in addition of the present invention is to use Pd to realize favourable technical effect in Ni base γ/γ ' alloy.
This above-mentioned first purpose is by being suitable for and will realizing that this alloy is γ/γ ' alloy, and be made up of following ingredients (weight %) at single crystalline, Ni directional solidification or many crystalline member base alloy that high temperature uses:
