Description
SPECIFICATION
Platinum group metal containing alloy
This invention relates to platinum group metal-containing alloys. In particular, the invention relates to nickel-chromium based gamma-prime alloys containing platinum group metal.
In our British Patent No. 1520630, we describe and claim certain nickel- and cobalt-based alloys containing platinum group metal and consisting essentially of (a) 40-78% Ni and/or Co, (b) trace-25% Cr, (c) trace-15% of platinum group metal and (d) trace-13% Al and/or Ti.
Such alloys possess a remarkably high temperature capability particularly in respect of their strength and creep resistance and are eminently suitable for such purposes as the fabrication of parts for use in the glass industry and in that part of the aero-engine industry concerned with jet engines and gas turbines.
We believe that the metallurgical structure of alloys according to said British Patent No.
1 520630 comprises a matrix of the nickel-chromium gamma phase including a minor proportion of the platinum group metal present, together with up to about 65% by weight of the gamma-prime phase which comprises principally tri-nickel aluminide (Ni3AI) substituted with platinum group metal, chromium and other alloying ingredients. Most-this is to say, probably in excess of 90%--of the platinum group metal is present in the gamma-prime phase and, we believe, is substituted predominantly for the aluminium constituent of said phase.
Although Ni3AI does not itself possess useful physical properties for rigorous applications such as those described above, it is nevertheless generally believed to be the presence of Ni3Al-that is to say, a gamma-prime phase, particularly such a phase also containing platinum group metal-in association with one or more other phases, which contributes to the said high temperature capability. It is also believed that alloys comprising a matrix of gamma-prime show enhanced temperature capability compared with alloys comprising a matrix of gamma interspersed with a precipitate of gamma-prime, but hitherto such alloys have tended to have relatively poor corrosion resistance, particularly at elevated temperatures. It is therefore an object of the present invention to provide a novel alloy which overcomes this disadvantage.
According to a first aspect of the invention, we provide a nickel- and chromium-based alloy consisting in percentages by weight and apart from impurities, of aluminium (4-13.5%), chromium (trace-6%), one or more metals of the platinum group (trace-20% total), balance nickel.
By "metals of the platinum group" we mean platinum, rhodium, iridium, ruthenium, palladium and osmium. Of these, we particularly prefer to use one or more of platinum, rhodium and ruthenium.
According to a second aspect of the invention, we provide an alloy according to the first aspect and also containing hafnium (trace-5%) and/or titanium (trace-6%) and/or tantalum (trace- 2%).
According to a third aspect of the invention, we provide an alloy according to either the first or second aspects and further containing from a trace to the weight specified of one or more of the following metals: niobium 6% carbon 0.15% boron 0.1% cobalt 10% molybdenum 14% tungsten 14% zirconium 1.75% Scandium, yttrium or oxides thereof and/or rare earth metals or oxides 3% silicon 0.25% magnesium 1% iron 10% manganese 0.25% vanadium 2%
It is to be understood that, in addition to the oxides of scandium, yttrium and the rare earths referred to above, other ingredients, for example Zr, of alloys according to the invention may be present at least partially as their oxides.The said oxides may either be added as such to the other alloying ingredients or may be formed in situ under the conditions of alloy formation.
One particular alloy according to the invention has the composition, in percentages by weight:
Al 7.3%, Ti 0.8%, Co 6.5%, Nb 0.99%, Mo 1.0%, Ta 10.5%, Cr 2%, W 2%, C 0.05%, B 0.01%, Zr 0.07%, Pt 7.5% and balance nickel.
Alloys according to the invention comprise a matrix of dendritic gamma-prime phase infilled with gamma and or beta, alpha, borides, carbides and so on indentritically, the precise structure depending on the aluminium content. We believe that the platinum group metal occurs at least in the gamme-prime and NiAI beta phases. The alloys can be produced by standard vacuum melting and casting techniques or by mechanical alloying, for example. A preferred method comprises uni-directional solidification, which enhances mechanical strength in the direction of solidification.
We have found that alloys according to the invention have a temperature capability of up to about 1100 C with respect to strength and oxidation resistance, which is superior to most conventional Ni-base superalloys and approximately comparable to prior art alloys comprising a matrix of gamma-prime. Alloys according to the invention also show enhanced hot corrosion resistance compared with most prior art conventional superalloys and also prior art gammaprime matrix alloys.
The following Table 1 gives examples of alloys according to the invention together with various prior art alloys. The figures for composition are based on weight added and it is to be understood that analysis of any given alloy would probably yield figures marginally different from those quoted.
