Description
Technical field
The invention belongs to field of compound material, is related to a kind of method for preparing aluminum matrix composite, in particular it relates to a kind of
Melt controls the preparation method of spontaneous aluminum matrix composite.
Background technology
In recent years, many articles have reported the research on in-situ authigenic reaction particles reinforced aluminum matrix composites.It is special
Putting is：Strengthen particle and combine preferable and clean interfaces in intrinsic silicon fabricated in situ, basal body interface；In-sltu reinforcement finer grain size
It is small (general<3.0 μm) and be evenly distributed in the base；By selecting reaction type and control response parameter, can obtain not of the same race
The In-sltu reinforcement particle of class, varying number；The fabricated in situ of enhancing particle combines with foundry engieering；Simple process, cost
It is low；It can be used to prepare the composite of definite shape and size.Find by literature search, Dacies P.Development of
Cast Aluminium MMCs (development of aluminum matrix composite), Key Engineering Materials (important engineering materials
Material), 1993,77:357-362, but there is strengthen phase particle size and skewness in prepared composite for this method
It is even；And mass fraction is not high, or work as TiB2When mass fraction is more than 8wt%, its institutional framework deteriorates, and casting character is deteriorated, material
The mechanical property of material substantially reduces.How size, distribution and the sedimentation segregation of enhancing phase is effectively controlled using rational technique
Report is there are no always.
The content of the invention
For in the prior art the defects of, it is an object of the invention to provide a kind of melt to control spontaneous aluminum matrix composite
Preparation method, solves aluminum matrix composite TiB2The problems such as strengthening the size of phase and being distributed controllable and sedimentation segregation.
The purpose of the present invention is achieved through the following technical solutions：
For the present invention by adding reaction adjuvant and multi- scenarios method technique containing melt alloying element, control reaction is auxiliary
Species, addition, proportioning, mixing speed, the reaction temperature added and the reaction time of auxiliary agent, and pulsed magnetic field and high energy surpass
The intensity collective effect of sound field, so as to realize enhancing phase TiB2The size of particle and distribution are controllable, and solve aluminum matrix composite
The sedimentation segregation problem of melt, and then prepare the aluminum matrix composite of even tissue and function admirable.
The invention provides the preparation method that a kind of melt controls spontaneous aluminum matrix composite, comprise the following steps：
After fine aluminium or alloy matrix aluminum fusing, reacting salt and reaction promoter are added, argon gas is blown into and stirs, is reacted；
Salt slag is removed after the completion of reaction, casts, produces after carrying out refining treatment.
Preferably, the preparation method also includes, by after matrix melts, adding 1-2wt% magnesium in the melt.
Preferably, it is 2 that the reaction promoter, which includes mass ratio,:1:1~4:1:1 Na3AlF6、LiF3、LiCl3。
Preferably, it is 1 that the reacting salt, which includes mass ratio,:1~2:1 NaBF4And Na2TiF6。
Preferably, the addition of the reaction promoter is reacting salt l 5-15wt%.The addition of reaction promoter is too high,
It can cause also uneconomical in the combined coefficient reduction and cost control of reaction；Addition is too low, can cause the TiB of generation2Particle
Size Distribution is discrete, lack of homogeneity.
Preferably, the argon flow amount is 5~15L/min, and speed of agitator is 250~350r/min.
Preferably, in the course of reaction, 1-5T pulsed magnetic field intensity is applied.
Preferably, in the course of reaction, 50-2000W/m is applied2High-energy ultrasonic field intensity.
Preferably, the reaction time is 10min~30min.
Preferably, the addition temperature of the reaction promoter is 720~760 DEG C.
Preferably, the reaction promoter is sufficiently mixed uniformly and dried before addition.
Present invention control enhancing phase TiB2Size and distribution, it is important to solve dynamics process in course of reaction.Anti-
During answering, melt temperature is controlled in the temperature range of relative narrower, and apply pulsed magnetic field and high-energy ultrasonic field simultaneously.
Solves TiB2The sedimentation segregation problem of reinforced aluminum matrix composites, its key point are how to prevent TiB2Particle leads to
Itself is crossed to reunite to reduce surface energy.Appropriate magnesium metal (content is about 1-2%) is added in the composite, makes particles generation
Reduce surface energy by adsorbing the magnesium in aluminium liquid first afterwards, then form preferable combination with aluminium again, so by the use of magnesium as
Particle surface energy is reduced, the means reunited is prevented, effectively slow down the phenomenon of particle sedimentation.Simultaneously because the addition of magnesium, makes
The viscosity increase of aluminium liquid, and according to Stocks formula, composite emulsion viscosities increase, the translational speed of particle reduces, when longer
It is interior to reunite because contacting with each other, also easily captured in process of setting by α-Al crystal grain, form stable homogeneous
Reinforcement.
Usual generated in-situ TiB2Particle is the particle of a diameter of 1 microns, and the particle of this size is in aluminium liquid
The appearance of sedimentation is not had.But because particle often generates in a certain regional area (on fused salt and the interface of aluminium liquid), very
Easily reunite because local concentration is higher.And once reunite and produce, then it is separately refined just very difficulty, in
It is just to have the segregation in sedimentation and process of setting.Using pulsed magnetic field and high-energy ultrasonic field is applied, melted using reaction
The protective effect of salt itself, pulsed magnetic field intensity control is controlled in 50-2000W/m in 1-5T, high-energy ultrasonic field intensity2.One
Aspect can increase the touch opportunity of fused salt and aluminium liquid, accelerate reaction, make generated in-situ TiB2Particle is uniformly tiny；The opposing party
Face promotes diffusion of the particle from the high concentration region of reaction to low concentration region, makes TiB2Particle uniformly and disperse, and then also causes multiple
The sedimentation phenomenon of condensation material has obtained certain alleviation.
Prior art is compared, and the present invention has following beneficial effect：The present invention is by melt alloying element and more
Coupling technique, solves TiB2Strengthen size, distribution and the sedimentation segregation problem of phase, be prepared for TiB2Granule content is up to 15%
Wt and the excellent aluminum matrix composite of structure property, while also prepare further opening up for particulate reinforced composite for salts reaction
Exhibition application provides foundation.
