The preparation method of the high performance magnesium alloy materials of the embodiment of the present invention, realize graphene and other metals member
Plain perfect compound, to form all good alloy material of various aspects of performance, concrete operation method is simply easily operated, front and rear step
Rapid linking is close, and operating condition is controllable, and each technological parameter has carried out strict control all in accordance with the concrete property of alloy material, non-
Often it is applied to the synthesis of alkene magnesium alloy materials.
In step (A), pure magnesium metal is first subjected to the pre-heat treatment, the temperature control of preheating is at 150-230 DEG C, so that it is more
Good merges with other metals, and the raw material of other metals can select corresponding metal powder to select ingot etc., the step
The index for needing strictly to control in rapid for melting temperature, it is necessary to be strict controlled between 900-950 DEG C, it is why so high
Temperature carries out melting and prepared also for subsequently being merged with graphene, if temperature is too low may to influence whether follow-up operation
Step is smoothed out, and magnesium and other metallic elements are carried out to carry out certain isothermal holding after melting, purpose also for
So that each raw metal preferably merges so that the performance of alloy is more stable, and the inert gas employed in the step can be with
For argon gas, nitrogen, helium etc., it can ensure that metal is not oxidized, strengthens its stability under inert gas shielding.
Preferably, for the time control being incubated in the step between 20-30min, the temperature of insulation is preferably controlled in 960 DEG C
More than, it is more excellent be 960-970 DEG C between because subsequently will with graphite alkenes material carry out compound, the guarantor of the step
Temperature can not be too low.
In addition, preferably first carry out certain pretreatment measure before the pure magnesium metal use of the present invention, in order to go
Except the impurity of magnesium based metal, stablize its performance, preferably merged with follow-up graphene with strengthening it, specific treatment measures are such as
Under：
Magnesium based metal is polished, polished, washed and the oil removing in alkaline solution, then washed again, nothing
After being cleaned 2-3 times in water-ethanol, cold wind drying.
The effect for removing impurity is can reach after being carried out according to above-mentioned steps to pure magnesium metal, moreover it is possible to reach and stablize pure magnesium gold
The purpose of attribute energy.
In step (B), the temperature of addition graphite alkenes material needs to control between 150-180 DEG C, this suitable temperature
What degree and inventor were obtained by largely groping experiment, in order that obtaining graphite alkenes material is preferably distributed to aluminium alloy
In, after graphite alkenes material first preferably is configured into the graphite alkenes material aqueous solution that mass percent concentration is 4-5wt%, then
The mixing of crude magnesium aluminium alloy is formed after being mixed with other metallic elements, if the graphite alkenes material aqueous solution concentration prepared certainly is too
Height, which may not reach, strengthens scattered effect, and concentration is too low and too many solvent can be introduced in system, therefore preferably quality
Concentration control between 4-5wt%, it is more excellent between 4.5-4.8wt%, in addition can also be 4.1wt%,
4.2wt%, 4.3wt%, 4.4wt%, 4.6wt% etc..
Preferably, ultrasonic disperse 1-3h after the addition graphite alkenes material aqueous solution, stands after being stirred for 1-3h, so operates
Purpose be for strengthening degree of scatter of the graphene in aluminium alloy, by ultrasonic disperse and churned mechanically operation most
The crude magnesium aluminium alloy obtained eventually is homogeneous, is produced substantially without agglomerated particle.
In the step, ultrasonic power is preferably controlled in 1000-2000w, and the speed of stirring is preferably controlled in 500-
Between 600rpm.
Finally, in step (C), crude magnesium aluminium alloy is refined, is surface-treated, is cold-pressed, the subsequent treatment such as sinter molding
Afterwards, that is, the high performance alkene magnesium alloy materials of the present invention are obtained, wherein cold pressing uses extrusion ratio as 15：1-20：Extruding between 1
Machine is carried out, and the cold press operation time is preferably controlled in 20-30min.
Preferably, the temperature control of sinter molding is between 350-500 DEG C.
Certainly, above-mentioned preparation method is to prepare the one of which preferably side of preparation of the high performance material of the present invention
Method, but no other preparation methods are not represented, as long as the alkene magnesium alloy materials of the performance with the present invention can be prepared
Process it is within the scope of the present invention.
In addition, each step has convenient manipulation temperature, manipulation time, these parameters in the preparation method of the present invention
Especially note that, be that inventor optimizes to obtain by a large amount of creative works, can not arbitrarily change, in step (A)
Smelting temperature and holding temperature it is higher, why so but the temperature in step (B) is dropped to than relatively low level,
If it is may have an impact because temperature is too high when adding graphene below to the performance of graphene in itself that gradient, which sets temperature,
Only strict control can just prepare the alloy material of the excellent properties with the present invention.
The report of alloy surface may be related to be attached in the prior art using graphene as coating, but so to alloy
Itself performance improvement effect it is very little, the present invention is that graphite alkenes material is directly penetrated into the inside of alloy, with magnesium with
And other metallic elements are sufficiently mixed and are integrally formed, such process technology does not have any report also in the prior art, and
The graphite alkenes material used of the present invention does not have concrete restriction, can pick out at random use as the case may be.
Compared with prior art, beneficial effects of the present invention are：
(1) the invention provides a kind of high performance alkene magnesium alloy materials, the alkene magnesium alloy materials by by graphene with
Magnesium metallic element and other metallic elements carry out composite synthesis, greatly improve the self-defect of former magnesium alloy materials, though
Right composition is simple, but performance is notable, for example, the performance indications such as heat resistance, intensity, hardness it is more traditional magnesium alloy materials it is equal
It is greatly improved, and also additionally imparts the excellent toughness of magnesium alloy materials, hot water resistance and far infrared performance；
(2) the alkene magnesium alloy materials with special component of the invention, yield stress can reach more than 400MPa, and tension is strong
Degree can reach more than 300MPa, and 700-800 DEG C of heatproof, hardness 120-140HV, density is in 1.5-1.6g/m3Between, it is seen that remove
There is excellent heat resistance, intensity, hardness, and density is smaller, it is than original magnesium alloy materials more more light, thus
The market application of magnesium alloy materials is further expanded, the added value of product in itself is improved, is also beneficial to entering for market
One step is promoted；
(3) preparation method of magnesium alloy materials of the invention realizes graphene and other metallic elements is perfectly multiple
Close, to form all good alloy material of various aspects of performance, concrete operation method is simply easily operated, and front and rear step linking is tight
Close, operating condition is controllable, and each technological parameter has carried out strict control all in accordance with the concrete property of alloy material, is highly suitable for
The synthesis of alkene magnesium alloy materials.
