Definitions
- the invention relates to a creep-resistant corrosion-resistant nickel-based alloy for Applications in high-temperature technology.
- a nickel-based alloy with the abbreviation NiCr 7030 accordingly DIN material number 2.4658 is considered to be heat-resistant and is used for heating conductors, Furnace components and the like used. Although such a material depending on Silicon and aluminum content has good oxidation resistance, this shows but low strength and low fatigue properties as well as high Creep values at operating temperatures of around 1000 ° C.
- This high-temperature, oxidation-resistant, massively embroidered, warm and cold-workable nickel-based alloy consists essentially of (in Mass%) 0.001 to 0.15 carbon, 0.10 to 3.0 nitrogen, 25.0 to 30.0 chromium, more than 0.3 to 1.2 nitrogen, 0.001 to 0.01 boron, 0.01 to 0.5 yttrium, cerium, Lanthanum, hafnium and tantalum, singly or in combination, balance nickel with one Share of at least 64.0%.
- the carbon content can indeed a Solid solution hardening can be achieved, the mainly effective elements
- the above alloy in terms of high temperature properties are Chromium and nitrogen. Chromium and nitrogen form chromium nitrides which form the Improve creep strength, with nitrogen in addition a Solid solution solidification yields. With the alloy according to DE-C-4411228 significantly improved creep strength and heat resistance values appear reachable.
- the object of the present invention is to overcome this deficiency eliminate and an improved nickel base alloy for To create high temperature applications.
- the advantages achieved by the invention are essentially based on the fact that In the material at temperatures up to 1200 ° C a grain boundary sliding by stable Excretions in the grain boundary areas largely prevented and a Increased solid solution hardening can be achieved. Furthermore, the adhesive strength the chromium spinel or the like layers on the surface increases, thereby an improved high temperature corrosion resistance of the parts is given.
- the elements of group 4,5 and 6 (except chromium), that are in essential titanium (Ti), zirconium (Zr), hafnium (Hf), vanadium (V), niobium (Nb), tantalum (Ta), molybdenum (Mo) and tungsten (W) act as solid solution strengthening agents and have different activities with respect to the non-metallic elements Carbon and nitrogen.
- Ta and Nb form thermally highly stable Nitrides, however, is the nitrogen affinity of the strong carbide formers Mo and W. low.
- a degree of solid solution hardening may be due to the carbon content and the content of strong carbide formers are adjusted. Is for example the Carbon content of the alloy low, become the strong carbide-forming elements Reinforced in the crystal lattice of the mixed crystals installed and brace this.
- Another important advantage of the alloy according to the invention is that the above-mentioned elements, in particular the elements Mo and W, shift the peritectic transformation of the II phase by substitution of Cr atoms to higher temperatures and thereby a stabilization of the II precipitates under conditions of use is effected.
- a transformation taking place at about 1000 ° C with increasing temperature ⁇ + ⁇ ⁇ ⁇ + ⁇ corresponding to ⁇ + Cr 13 Ni 7 N 4 ⁇ ⁇ + Cr 2 N
- Ni-Cr-N alloys which is associated with a volume change of about 1 ⁇ 10 -3 %, as shown in Table 1, by a Mo concentration of 4% by weight to a temperature of raised above 1210 ° C.
- Carbon containing greater than 0.0015% by weight promotes the nitride and Carbonitride, but withdrawn at a content of greater than 0.6 wt .-% of Alloy too large amounts of carbide-forming elements, causing a Counteracts matrix solidification. Preference is given to carbon contents of 0.16 to 0.5% by weight.
- the ratio nitrogen - to carbon content in the Alloy in the range of 0.5 to 5.5, preferably 1.0 to 4.0, optionally 1.0 to 3.0, will be particularly effective and stable Carbonitride precipitates formed and efficient solid solution hardening reached.
- the material is at least 0.03 wt .-% Al and at least 0.4 wt .-% Si. Higher levels than 3.0 wt .-% Al lead to an adverse excretion behavior, stress cracks and a Coarse grain formation and contents higher than 3.0% Si deteriorate the Thermoformability of the alloy.
- the corrosion resistance at high temperatures is increased in the the material with elements of group 3 of the periodic table, which are Scandium (Sc), yttrium (Y) lanthanum (La) and lanthanide in one concentration from 0.01 to 0.12% by weight is alloyed.
- Sc Scandium
- Y yttrium
- La lanthanum
- lanthanide in one concentration from 0.01 to 0.12% by weight is alloyed.
- Nickel-base alloys with a composition according to the invention can with the help of pressure metallurgy, in which the liquid melt until solidification the same is kept under high pressure (eg DESU method) or powder metallurgically produced.
- pressure metallurgy in which the liquid melt until solidification the same is kept under high pressure (eg DESU method) or powder metallurgically produced.
- a deformation of the cast or sintered block is usually after one Homogenization of the material at 1250 ° C with a forming at 1200 ° C.
- grain sizes of 35 to 80 microns and nitride precipitates with a Diameter of 1 to 5 microns created in the material.
- the transition temperature of the II phase by a Presence of elements of group 4,5 and 6 increased.
- Tab. 1 are the determined dissolution and formation temperatures, the composition the II phase and that of the - mixed crystal for a Mo-free Ni-Cr-N alloy and for those with a Mo content of 4 and 8 wt% and one with 4 wt% W specified.
- concentrations of 8 wt .-% Mo and 0.7 wt .-% N are For example, both temperature values for a ⁇ ⁇ ⁇ conversion above 1300 ° C.
- the II phase has a reduced chromium content of 45 wt .-% at a molybdenum concentration of 11 wt .-% on.
- the ⁇ -mixed crystal has increased chromium values of 29% by weight and a molybdenum content of 6.5% by weight at a reduced nickel concentration. Influence of the molybdenum and tungsten content on the interval of the ⁇ + Cr 2 N transformation temperature ⁇ T (dilatometer investigations) Chemical composition [wt.
- Table 2 shows the chemical composition of the invention Alloys (Legs 1 to 5) and comparative alloys (Legs 6 to 9).
- the resistance to high temperature corrosion was improved by about 16% (Alloy 3 by more than 22%) in the alloys of the present invention over those of the prior art.
