Definitions
- the invention relates to an austenitic nickel-chromium-cobalt-molybdenum-tungsten alloy.
- nickel-based alloys have a widespread use in heat engines, e.g. Combustion engines, stationary and flying gas turbines can be found because they have extraordinarily good strength properties, especially in the temperature range of 700 - 900 ° C.
- alloys contain significant amounts of ⁇ '- and ⁇ "phases, which make a decisive contribution to increasing strength in the temperature range of 700 - 900 ° C.
- the alloy elements aluminum, titanium, tantalum are usually used to eliminate the ⁇ '- and ⁇ " phases and used niobium.
- GB-A 929,687 is a nickel-chromium-cobalt-molybdenum alloy which, through the addition of 2.0-3.5% titanium, 0-0.8% aluminum and 2-5.25% niobium, results in a significant increase in strength ⁇ '- and ⁇ "excretion will help.
- Tungsten is approved as a substitution element of molybdenum up to 10 atom%, tantalum up to 3% by weight is proposed as a substitution element of niobium.
- GB-A 1, 036, 1 79 essentially describes only a limitation of the elements specified in GB-A 929,687, with the exception that iron is no longer permitted as an alloying element.
- US Pat. No. 4,981,644 also describes a nickel-chromium-cobalt-molybdenum alloy which is precipitation-hardening due to titanium, aluminum, niobium and tantalum, but only has a total content of 1.0 with respect to the elements rhenium, molybdenum and tungsten - prescribes 8.5%.
- WO-A 90/03450 describes a precipitation-hardening alloy in which not only upper but also lower limits are specified for the precipitation-hardening elements AI, Ti, Nb and Ta in comparison to US Pat. In contrast, rhenium, hafnium and vanadium are only set with an upper limit.
- GB-A 1, 336.409 describes a nickel-chromium-cobalt-molybdenum alloy in which the sum of the precipitation-hardening elements aluminum and titanium is limited to 0.8-2.1%.
- EP-B 0633 325 discloses an alloy based on US-A 4,877,461 for a nickel-chromium-cobalt-molybdenum alloy in addition to limiting aluminum and titanium to 0.5-2.0% by weight. and the addition of max. 5% by weight of tungsten 0.7-2.5% by weight of tantalum proves to be advantageous for the strength.
- the material should be used as a formable and weldable wrought alloy.
- Chromium 21 to 23%
- Molybdenum 1 0 to 1 1%
- Titan max. 0.50%
- Nickel rest including unavoidable melt-related contaminants.
- a preferred austenitic nickel-chromium-cobalt-molybdenum-tungsten alloy (in% by mass) has the following composition
- Chromium 21 to 23%
- Molybdenum 1 0 to 1 1%
- Titan max. 0.50%
- melt-related contaminants including unavoidable melt-related contaminants.
- the nickel-chromium-cobalt-molybdenum-tungsten alloy according to the invention has significantly more than 5% by mass of tungsten and dispenses with the addition of tantalum to improve the heat and creep resistance. Alloying from 0.01 to 0.1 mass% yttrium also improves the cyclic oxidation resistance.
- the nickel-chrome-cobalt-molybdenum-tungsten alloy according to the invention is particularly suitable for objects such as e.g.
- the objects mentioned can be easily manufactured from the material according to the invention, since it is not only readily thermoformable, but also for cold processing operations - such as Cold rolling to thinner dimensions, folding, deep drawing, flanging - has the necessary forming capacity.
- FIGS. 1 to 4 show very clearly, on the basis of the lifetimes achieved at 700 ° C., 750 ° C., 800 ° C. and 850 ° C. in the stress rupture test, the superiority of the alloys 1-4 according to the invention compared to the prior art representing alloys 5 - 7.
- composition of alloys 1-7 is shown in Table 1.
- the alloys according to the invention have been alloyed with yttrium.
- the content of 0.01 to 0.1% according to the invention results from the minimum content of 0.01%, which is necessary for a visible improvement effect, and the maximum content specified at 0.10%, beyond that with 'overdoping' and in turn a deterioration in the cyclical resistance to oxidation can be expected.
- the positive effect of the yttrium is confirmed by the significantly lower mass increase shown in FIGS. 5-6 in the cyclic oxidation test at 700 ° C. and 800 ° C. over a test time of more than 1,000 hours.
