Description
The present invention relates to granular composition, wherein particle has continuous metal phase, for example aluminium alloy.

European patent application specification EPA128260 has introduced the technology of metallic vapour manufacturing less than 10 microns composition grain that adopt.
BP GB2115014 has introduced molten metal drop and has combined the method for making block (promptly not being particle) product with the particulate refractory material.
Germany patent DE2124199 has introduced the spray method of making metal dust, and its particle surface scribbles the refractory material of particulate.
European patent application specification EPA147769 has introduced the aluminum alloy granule shape method for compositions that has the particulate refractory material with the manufacturing of physical method alloying.
BP GB1548616 is one of relevant patent series of making the sprayed deposit prefabricated blank, and prefabricated blank is by the goods that for example forge, compacting or machining can be produced precise measure thus.Flow with the high-speed gas atomization molten metal alloy, and the collection surface of resulting thermometal particle mist directive shaping is formed the deposit that solidifies.This patent has been introduced a part of particle and how have been failed to hit the target, and builds up the powder or the agglomerate of spray material, and they both had been not easy to reclaim, and self-evident, can not be used for other purposes.
European patent application specification EPA198607 has introduced manufacturing metallic matrix method for compositions, and it comprises the steps: to make the atomizing of motlten metal stream and the mist of formation thermometal particle with quite cold gas directive motlten metal stream; Fine solid particles to this metal flow or mist importing different metal composition material; And have above-mentioned fine grained and mix wherein metal to freeze solidly on the form deposition of collecting the surface.Fine particle materials has improved the physical property and the mechanical performance of metallic matrix.Metal can be an aluminium, and granular materials can be SiC.
When pressing the method operation of european patent application specification EPA198607, there is the metallic particles of part not to be deposited on the collection surface usually, and builds up powdered or agglomerate in the downstream.The present invention is based on following relevant observation of crossing spray, when refractory material in small, broken bits imports motlten metal stream or mist, find that refractory material does not exist only in to collect the surface and go up solidifying in the deposit of forming, and be mixed in the metal of spray.This refractory material is present in the overspray, not only on the surface of metal particles of solidifying, and quite is evenly distributed in the inside of particle.This observed result is beyond thought, does not recognize that in the past refractory material combined with the melt metal mist before depositing to the collection surface unexpectedly.In fact, above-mentioned prior art is never pointed out this kind fixation phenomenon can take place.
The invention provides to be dripped with the particulate refractory material by motlten metal and combine the granular composition of making, wherein particle contains continuous metal phase, and the disperse phase that fuses the refractory material in continuous phase.
When metal was aluminium alloy, the present invention had special importance, and is fairly good because the technical development of atomized molten aluminium alloy gets.But the present invention also is applicable to spray and is some other material that shape is dripped in fusion, for example, and steel, nickel, cobalt, copper, titanium and magnesium.
Drip to combine by motlten metal and made granular composition with the particulate refractory material.Even when spraying casting in inert atmosphere, with regard to aluminium alloy, the particle of generation must have thin oxide at least and cover on their surface.If in the particulate refractory material, deliberately do not add the field trash of oxide, then can not contain the oxide inclusion of any inherence in the particle usually.On the contrary, the aluminum alloy granule shape composition by the manufacturing of physical method alloying but must contain inherent oxide inclusion.
The particle of composition generally has the particle diameter of 10 to 500 micrometer ranges, and 20 to 80 microns average diameter is preferably arranged.As known in this technical field, when forming particle with the spraying casting, the diameter of condition control particle that can be by the control atomizing.Though particle can flatten, for example, the result of splash casting, the particle of composition it would be desirable spherical.
Refractory material can be fusing point other metal higher than this metal, but it would be desirable oxide, boride, carbide or nitride.As everyone knows, with regard to this class ceramic material, some of them are referred to as refractory metal, and best example comprises SiC, Al
2O
3, MgO, TiC and boron carbide.These refractory materials preferably use with graininess, and the average diameter of particle is less than 50 microns, until submicron-scale.5 to 20 microns particle is often easy to use.
In composition grain, disperse phase and continuous phase preferably are respectively 0.5 to 50% and 99.5 to 50% volumetric concentration.Especially when the volumetric concentration of using 10 to 30%, the refractory powder of high strength and modulus can invest sizable reinforcement of composition and modulus properties.
Parent metal can be the aluminium alloy that contains one or more common age-hardening compositions and solution strengthening composition, for example Zn, Mg, An, Si, Li, and also can contain one or more transition metals arbitrarily in order to reach the grain refinement purpose.
Perhaps aluminium alloy can contain a kind of alloying composition of transition metal at least, and these alloying compositions have age-hardening, or the performance of solution strengthening, for example Cr, Zr, Mn, Fe, Co and Ce.It would be desirable that alloy contains 0.5% to 7%(weight) Cr, 0.5% to 2.5%(weight) Zr and 0.1% to 4.0%(weight) Mn.These alloying compositions are difficult to make them to be dissolved in the solid solution of aluminium with common method, but can solve this difficult problem by the spraying casting technique of introducing below.The alloy element of these transition metal has the advantage that the high-temperature aging hardening capacity is provided in 300 ℃ to 500 ℃ scopes.
The alloying composition of best transition metal is to small part, and the solid solution interior (oversaturated) that preferably all is present in metal.When not in solid solution, these alloying compositions should exist with thin dispersion form.For this reason, must cool off melt metal fast,, cool off fast, so that make the solid solution of alloying composition with the speed of 10 ℃ of about per seconds so that obtain thin dispersion with the speed of 10 ℃ of about per seconds.The cooling velocity that the spraying casting can reach depends on granularity.
On the other hand, the invention provides a kind of method of making granular composition described herein, this method comprises with quite cold gas directive motlten metal stream, make the atomizing of motlten metal stream and the spray of formation metallic particles, refractory material to this metal flow or spray importing fine solid particles, metallic particles is solidified, and collect the granular composition that is produced.
It would be desirable before motlten metal stream just will be dispersed into spray, go into the refractory material of solid particle to the motlten metal conductance.In order to obtain spherical particle, certainly metallic particles must it with the collision of any surface of solids before curing earlier.With regard to aluminium alloy, perhaps argon gas is suitable inert gas, or nitrogen is optimal inert gas.If the partial pressure of oxygen that provides is enough low, then composition grain will be spherical, and thin aluminium oxide cover layer is only arranged.The particle spray directive of motlten metal can be collected the surface, in the case, granular composition be reclaimed as byproduct.In other words, can select spray condition like this, so that metallic particles solidified earlier before with any surface of solids collision.
It is not high that the present invention requires aluminium alloy capability.We have made and have made granular composition in this way, and the raw material that is adopted is refractory material SiC and the following material: commercial fine aluminium, AA2014,2024,2618,6061,7075,7475,8090, LM13, A3210, Al-12%Si, Al-20%Si and Al-6%Sn.
That this granular composition is suitable for is for example canned with known powder metallurgy process, the degassing, compacting and extruding, further is processed into the solid such as semifinished or finished goods.Applicable method comprises and directly is squeezed into the air frame construction; Extruding rod and the compressor blade that forges into gas turbine, or the piston of internal combustion engine; Or stripper plate and be rolled into the metallic plate that airplane skin is used.
Now consult and be applicable to the atomising device figure that makes granular composition of the present invention.This device comprises the nozzle 10 of motlten metal, and motlten metal flows 12 mat gravity and passes through this nozzle.What center on this motlten metal nozzle is a gas nozzle 14 with holes, derives carrier gas stream 16 by its perforate, and it is parallel and center on metal flow, shields and surround this motlten metal.What center on a gas nozzle is the secondary air nozzle 18 that jet pipe 19 is housed, and makes secondary-atomizing air-flow 20 directive motlten metals stream by jet pipe.Secondary gas flow contacts with motlten metal stream at the downstream part of distance motlten metal nozzle h, and makes motlten metal stream be atomized into the spray 22 of metallic particles.
Secondary-atomizing air-flow 20 has been determined a taper shape, and its height is h, and radius equals the distance of jet pipe 19 and metal flow 12.The refractory material 24 that uses carrier gas to carry is introduced this cone by pipe 26.The flow velocity of carrier gas is generally less than the several magnitude of secondary-atomizing gas 20.
The position that carrier material is introduced cone does not have strict the qualification; For example it can be in the inboard of a gas nozzle 14, rather than in its outside.If the h distance is enough little, then a gas nozzle just can be exempted fully.
The refractory material of carrier band in the carrier gas, the refractory material concentration in the granular composition that flow rate of carrier gas suitable with flow rate of metal and secondary (atomizing) gas flow rate have determined to be produced.The temperature of atomization gas and flow velocity have determined the freezing rate of atomization metal particle.
