Definitions
- the invention relates to a Mo-Si-B alloy consisting of the intermetallic phases molybdenum silicide and molybdenum borosilicate, optionally additionally molybdenum boride, the total content of intermetallic phase components being 25 to 90% by volume and the proportion of other structural components being ⁇ 5% by volume and the rest consists of molybdenum or mixed molybdenum crystal.
- Molybdenum and molybdenum alloys are widely used in industry because of their good mechanical strength properties at high temperatures. A problem with these alloys is their poor resistance to oxidation at temperatures above about 600 ° C.
- the known measures for improving the oxidation properties are correspondingly diverse. They range from the application of superficial protective layers to alloying measures.
- EP 0 804627 describes an oxidation-resistant molybdenum alloy which consists of a molybdenum matrix and intermetallic phase regions dispersed therein from 10 to 70% by volume Mo-B silicide, optionally up to 20% by volume Mo-boride and optionally up to 20 vol.% Mo silicide exists.
- the alloy comprises the elements C, Ti, Hf, Zr, W, Re, Al, Cr, V, Nb, Ta, B and Si in the form that one or more elements from the group Ti, Zr, Hf and Al must be present in the Mo mixed crystal phase in a proportion of 0.3-10% by weight.
- the alloy can optionally contain up to 2.5 vol.% Carbide.
- the alloy can be manufactured by various methods, preferably by means of powder metallurgical methods or by means of layer deposition methods. Alloys according to EP 0804627 form a borosilicate layer at temperatures above 540 ° C, which prevents further penetration of oxygen into the interior of the body.
- the addition of elements such as Ti, Zr, Hf or Al promotes the wetting of the boron-silicate layer, increases its melting point and leads to the formation of a high-melting oxide layer below the boron-silicate layer, which reduces further oxygen transport into the interior.
- the addition of carbides leads to an increase in mechanical strength. A serious disadvantage of such alloys is their low fracture toughness.
- alloys with an optimum silicon and boron content with regard to their oxidation resistance can no longer be produced using forming technology.
- the material according to the invention consists of the intermetallic phases molybdenum silicide and molybdenum boron silicide, optionally also molybdenum boride and molybdenum or molybdenum mixed crystal.
- Other structural components are also possible, although tests have shown that their volume content must be ⁇ 5%.
- Mo 3 Si and Mo 5 SiB 2 may be mentioned as preferred molybdenum silicide or molybdenum boron silicide phases.
- Oxides or mixed oxides, which have a vapor pressure of ⁇ 5x10 "2 bar at 1500 ° C, are finely distributed in this alloy matrix.
- the preferred mean particle size is ⁇ 5 ⁇ m.
- oxide additives in Mo-Si-B alloys not only increase the strength, as is customary in the case of ODS alloys, but surprisingly also to a high degree the ductility properties.
- Alloys with the structure according to the invention have an elongation at break which is at least 3 times higher at 1200 ° C. than Mo-Si-B alloys according to the prior art with the same silicon and boron content, but without the oxide additives according to the invention.
- a steam pressure at 1500 ° C of ⁇ 5x10 "2 is required to ensure adequate processability guarantee.
- the preferred oxides are: Y 2 O 3) ZrO 2 , Hf0 2 , TiO 2 , Al 2 O 3 , CaO, MgO and SrO.
- the alloy according to the invention can contain elements which form a mixed crystal with molybdenum. These include Re, Ti, Zr, Hf, V, Nb, Ta, Cr and AI. An Nb addition has proven particularly advantageous.
- Nb 5 atomic% Nb to a Mo-Si-B alloy with 8.8 atomic% Si and 7.6 atomic% B and 0.5 vol.% Yttrium oxide, the tensile strength can be changed at a test temperature of 1000 ° C 5% can be increased while increasing the elongation at break by 80%.
- the silicon and boron contents are advantageously chosen so that the composition in the three-substance system molybdenum silicon boron is in the range Mo-Mo 3 Si-T 2 (Mo 5 SiB 2 ) - Mo 2 B. This is the case if the Si content is 0.1-8.9% by weight and the B content is 0.1-5.3% by weight.
- a particularly advantageous concentration range in terms of strength, creep resistance, fracture toughness and oxidation behavior is 2-6% by weight Si, 0.5-2% by weight B and 0.2-1% by volume oxide.
- Powder mixtures consisting of the corresponding components are treated by mechanical alloying, whereby both elementary powders and pre-alloyed powders can be used.
- Usual high-energy mills such as attritors, ball mills or vibrating mills are suitable as units.
- Hot isostatic pressing has proven itself as a compacting process.
- the ground powder is poured into a Mo alloy jug, welded in a vacuum-tight manner and compacted at temperatures in the range of 1300 ° C - 1500 ° C.
- Other pressure-assisted hot compacting processes, such as powder extrusion can also be used.
- melt metallurgy manufacturing processes can also be used. Particularly noteworthy are spray compacting processes where oxide additives are added during the spray phase.
- 0.5% by weight of yttrium oxide powder with a mean grain size according to Fisher of 0.8 ⁇ m was mixed with 96.5% by weight of Mo with a grain size of 4.12 ⁇ m, 3.1% by weight of Si with a grain size of 4.41 ⁇ m and 1, 14 wt.% B with a grain size of 0.92 ⁇ m and mechanically alloyed.
- Mechanical alloying was carried out in an attritor under hydrogen. The attritor volume was 50 l and 100 kg balls made of a Fe-Cr-Ni alloy with a diameter of 9 mm were used. The attraction time was 10 hours. After mechanical alloying, only molybdenum and Y 2 Ü3 could be detected using XRD.
- the powder was placed in a jug made of an Mo-based alloy.
- the jug was evacuated and vacuum-sealed.
- the jug and powder were heated to a temperature of 1500 ° C. in an indirect oven and compacted by extrusion.
- the extrusion ratio was 1: 6.
- Tensile specimens were worked out from the extrusions thus produced by means of erosion and turning processes.
- a material without yttrium oxide was also produced for comparison purposes, the process steps mentioned above being used.
- the samples according to the invention and the comparative samples were characterized by a hot tensile test, the elongation rate being 10 '4 seconds "1.
- the test temperature was increased successively until a temperature could be determined at which the elongation of the tested sample was at least 10%.
- a temperature of 1000 ° C. could be determined in the sample according to the invention. For the material without the addition of oxide, this was 1300 ° C. The corresponding strength values at 1300 ° C were 300 MPa for the sample according to the invention and 200 MPa for the sample without added oxide.
- La (OH) 3 powder with an average grain size of 0.2 ⁇ m was mixed with 93.9% by weight of Mo with a powder grain size of 4.25 ⁇ m, 3.9% by weight of Si with a powder grain size of 4.30 ⁇ m and 1.4% by weight of B with a powder grain size of 1.15 ⁇ m and mechanically alloyed. Mechanical alloying was again carried out in an attritor under hydrogen for 10 hours. The powder was cold isostatically pressed at 2000 bar and then compacted by a sintering treatment at 1350 ° C. for 5 hours under hydrogen. The determination of the density showed that 91% of the theoretical density (8.7 g / cm 3 ) could be achieved.
