Description
Technical field
The present invention relates to high-strength, the high-ductility Ni of one kind50Mn34In16-xCoxThe preparation method of Magnetic Memory alloy.
Background technology
1996, Ullakko et al. was first in Ni2Obtained in MnGa monocrystalline about 0.2% reversible strain, pull open since then
The research prelude of magnetic driven memory alloy, the study hotspot as marmem field.Current research is wide
Magnetic driven memory alloy mainly includes：Ni-Mn-Ga (Al), Ni-Fe-Ga, Co-Ni-Ga (Al) and new Ni-Mn-In
(Sn, Sb) alloy.Ni-Mn-Ga based alloys be find earliest, be also to study most commonly used magnetic marmem at present, its
Magnetic-field-induced strain derives from martensitic twin variant under external magnetic field and resets the macro-strain produced, with such a deformation mechanism
Alloy to obtain the key of big magnetic-field-induced strain be with high magnetocrystalline anisotropy energy and low twin boundary migration limit stress.
At present in Ni-Mn-Ga series alloys, monocrystalline maximum reversible strain property reaches 10%, but due to defeated produced by variant rearrangement
Go out stress smaller, only 2MPa or so, it is difficult to meet the application requirement of Practical Project.In the recent period, new magnetic driven memory alloy system
Ni-Mn-X (X=In, Sn, Sb) causes the attention of various countries researcher.The serial Heulser alloys are in nonstoichiometry ratio
With thermoelastic martensitic transformation, magnetic truly is realized in certain composition range or after the ferromagnetic Elements C o of doping
Driving phase transformation, produces macro-strain, and it is larger that the essence of the series alloy magnetic-field-induced strain is that martensitic phase has with parent phase
Saturation magnetization is poor, and alloy transformation temperature is significantly reduced under external magnetic field, applies external magnetic field in certain temperature range
Martensite reverse transformation can then be brought it about so as to have SME, and export larger stress.But Ni-Mn-In is closed
Golden system still suffers from fragility greatly, and the threshold value of field drives phase transformation is high, and the low defect of Curie temperature limits it to a certain extent
Practical application.So how to improve magnetic field life strain, field drives threshold value is reduced, improves alloy mechanical performance, obtains big
Magnetic entropy becomes and giant magnetoresistance effect, it has also become the main direction of studying that memorial alloy is applied and developed.
Refined crystalline strengthening can significantly change alloy transformation temperature and improve its mechanical performance and physical property.Therefore gold is passed through
Belong to injection moulding and sintering process combines and prepares Ni50Mn34In16Magnetic Memory alloy improves alloy mechanical property and improves magnetics
One of effective ways of performance.
Metal injection moulding (Metal Injection Molding, abbreviation MIM) is a kind of from injection molding of plastics industry
In the novel powder metallurgy forming technique extending out, it is well known that the cheap price production of injection molding of plastics technology is various
The product of complicated shape, but plastic products intensity is not high, and in order to improve its performance, metal or ceramic powder can be added in the plastic
End is to obtain the product that intensity is higher, wearability is good.In recent years, development evolvement is to improve solid to greatest extent to this idea
The content of particle and in subsequent sintering process completely except no-bonder and make shaping base be densified.
The content of the invention
In order to solve existing Ni-Mn-In-Co suitable shape memory alloys fragility greatly, the problem of driving magnetic field threshold value is high,
The present invention provides one kind and combines to prepare Ni by metal injection moulding and sintering process50Mn34In16-xCox(x=2,3,4,5)
The method of Magnetic Memory alloy.
The marmem of the present invention is prepared as follows：According to atomic percent take 50 parts Ni powder, 34
The Mn powder, 11-14 parts of In powder and 2-5 parts of Co powder of part, it is well mixed by agitator, then add a certain amount of binding agent and carry out
Mixing, it is last degreasing sintered then by metallic injection machine injection moulding, Ni is made50Mn34In16-xCox(x=2,3,4,
5) Magnetic Memory alloy.
More specifically, Ni of the present invention50Mn34In16-xCoxThe preparation method of (x=2,3,4,5) Magnetic Memory alloy is as follows：
Before sintering, Ni powder, Mn powder, In powder and Co powder that particle diameter is 300 mesh is taken to mix according to atomic percent, with 200 in agitator
Turn/metal dust is well mixed to stir by min-500 turns/min, then adds metal dust gross mass 2%-5% binding agent
It is sufficiently mixed uniformly with metal dust, be then added in metallic injection machine, make to glue by being heated to 200 DEG C -400 DEG C
Tie agent to melt, then 20-40 kilograms of pressure 10h-48h applied to mould, obtain injecting embryo, finally will injection base through degreasing at
Reason, uses 1500 DEG C -1700 DEG C of temperature, 200-400 kilograms of pressure, vacuum for 10-3-10-4MPa, the time is 20-40 minutes
Sintering process is sintered, and finally obtains the Ni that particle diameter is about 50-60 microns50Mn34In16-xCox(x=2,3,4,5) Magnetic Memory alloy.
It is preferred that, the binding agent is epoxy resin and polyamide with 4：1 mass ratio is mixed.
Binding agent is the core of Metal Injection Molding, and binding agent has enhancing mobility to be adapted to injection in MIM
The effect of briquet shape is molded and maintains, it should also have the features such as readily removed, pollution-free, non-toxic, cost is reasonable in addition,
Various binding agents are occurred in that for this, Recent study personnel are just gradually selected to according to degreasing method from rule of thumb
And the requirement to binding agent function, the direction for targetedly designing binder system is developed.Inventor is by repeatedly
Test of many times, draws most suitable Ni50Mn34In16-xCoxThe binding agent of (x=2,3,4,5) Magnetic Memory alloy, in the binding agent
Under effect, make metal dust that there is good cavity filling, while having good degreasing, make the consistency of alloy high, burning
Good performance is obtained after knot.Ni50Mn34In12The crystal grain that the reason for Co4 gold excellent in mechanical performance is mainly alloy is more tiny, and
And (Co, Ni) is occurred in that in the alloyxThe phases of In second, therefore the mechanical property of alloy is greatly improved.
Beneficial effect
The marmem Ni that the inventive method is prepared50Mn34In16-xCox(x=2,3,4,5) different existing warps
Magnetic shape memory alloy Ni prepared by arc melting method50Mn34In16-xCox(x=2,3,4,5), and by comparison have with
Lower advantage：
Ni prepared by the present invention50Mn34In16-xCox(x=2,3,4,5) alloy has higher fracture strength and fracture should
Become, the magnetic shape memory alloy fine microstructures, good toughness, intensity is big, with excellent magnetic performance, is high temperature high-ductility shape
The application extensions of shape memory alloys thinking.
