Description
Technical field
The present invention relates to amorphous composite material or technical field of high-entropy, specially a kind of high entropy amorphous-dendrite of Ti base
The preparation method of composite material.
Background technique
Amorphous alloy, also known as glassy metal are a kind of materials with many novel performances.Amorphous state refers in substance
Portion's atomic structure is in the ordered state of longrange disorder, shortrange order.Different from conventional oxide glass, atom in amorphous alloy
Between associative key be metallic bond, and non-covalent bond.Since its unique disordered structure makes it not have crystalline material Dislocations, sky
The defects of position, therefore, amorphous alloy, have excellent mechanics, physical and chemical properties, such as high intensity (about 1/50 Young
Modulus), high corrosion resistance, the superplasticity under excellent magnetic performance and certain temperature.These excellent physical chemistry and power
Characteristic and good forming characteristic are learned, so that amorphous alloy is in electronics, electric power, chemical industry, Aeronautics and Astronautics, machinery and microelectronics
Equal fields have wide application space.However the room temperature brittle failure of amorphous alloy and stability seriously constrain its engineer application.
Traditional amorphous alloy usually has a host element, in recent years, by five kinds or five kinds or more elements according to etc.
The amorphous alloy that the atomic ratio alloyizations such as atomic ratio or approximation are formed is known as high entropy amorphous alloy.High entropy amorphous alloy is in addition to having
Other than the advantages of amorphous alloy mentioned above, it is higher that high entropy effect has high entropy amorphous compared to traditional amorphous alloy
Intensity, by taking Ti-Zr-Ni-Cu-Be system as an example, Ti20Zr20Ni20Cu20Be20High entropy amorphous compressive strength up to 2300MPa,
And traditional amorphous alloy compressive strength maximum of same system only 2000MPa;High entropy amorphous is another compared to what traditional amorphous had
One advantage is that its thermal stability is more preferable, i.e., high entropy amorphous is changed into required for crystal structure as amorphous structure under the same terms
Time it is longer.These excellent physical and mechanical properties make high entropy amorphous alloy become a kind of potential Engineered Wood Products
Material.
High entropy amorphous alloy can be used as a kind of new structural material and use, it is necessary to it is required that it is with certain plasticity,
To guarantee the safety used.But until 2017, existing document showed that almost all of high entropy amorphous alloy all has
Very low plasticity.It has been generally acknowledged that the main reason for limiting high entropy amorphous plasticity is that it lacks the dislocation movement by slip, twin in crystalline material
The Plastic Deformation Mechanisms such as raw, the single shear-deformable of height localization can occur for high entropy amorphous in deformation process, and along cutting
It cuts band and brittle fracture occurs.Its plastic strain is almost nil in a stretched state for usually most of high entropy amorphous alloy, compresses shape
Plastic strain is again smaller than 2% under state.Just because of being difficult to obtain high tough high entropy non-crystalline material, in recent years to the high entropy amorphous of raising
The research of alloy ductility is more and more.
In general, it is a kind of effective of the high tough non-crystalline material of acquisition that the second phase, which is precipitated, in introducing original position in traditional non crystalline structure
Approach.Principle is to inhibit the unstable propagation of single shear band using generated in-situ second phase, promotes its multiple bifurcated and extension,
This process makes in amorphous alloy there are the shear band of a large amount of different orientations to provide effective plastic deformation ability.Institute
It is the raising for being very beneficial for mechanical property so that the second phase dendrite to be formed in situ in amorphous alloy.
Since the amorphous formation ability of high entropy amorphous is much smaller than traditional amorphous alloy, it is with Ti-Zr-Ni-Cu-Be system
Example, Ti20Zr20Ni20Cu20Be20High entropy amorphous maximum critical dimension is only 3mm, and Ti40Zr25Ni3Cu12Be20Traditional amorphous
Maximum critical dimension can reach 14mm.By introducing the preparation in situ that the second phase is precipitated and obtains high tough material in non crystalline structure
Method requires amorphous system to have good amorphous formation ability, therefore passes through in the limited high entropy amorphous of amorphous formation ability
It is more difficult that second phase of introducing in situ prepares dendrite amorphous composite material.
