Description
Technical field
The invention belongs to amorphous alloy material field, relates in particular to a kind of raising Ce base bulk metallic glass room temperatures
The method of plastic deformation ability.
Background technology
Since the eighties of last century sixties, glassy metal was found, glassy metal is unique better than common alloy with it
Mechanical property, magnetic performance, corrosion resistance, good biocompatibility etc., and receive the very big concern of Material Field.
Glassy metal has completely unordered structure, lacks the fault of construction such as crystal boundary, dislocation in crystalline material.Amorphous state knot
The fracture mode of glassy metal is often brittle fracture when structure determines room temperature, and this brittle fracture pole for having no sign is unfavorable for
The engineer applied of glassy metal.The brittle fracture of glassy metal is important scientific issues urgently to be resolved hurrily, especially for Ce- bases
This kind of strong glass former system of bulk metallic glass, room temperature compression often show brittle fracture.Therefore, finding one kind can increase
The method of Ce- base bulk metallic glass temperature-room type plasticity deformabilities is added to be particularly important.
The content of the invention
To avoid the weak point present in above-mentioned prior art, the invention discloses one kind to improve Ce base bulk metal glass
The method of glass temperature-room type plasticity deformability.
The present invention adopts the following technical scheme that to realize goal of the invention：
The invention discloses a kind of method of raising Ce base bulk metallic glass temperature-room type plasticity deformabilities, its feature exists
In：Described Ce bases bulk metallic glass is Ce by the structural formula of the atomic percentage of each element69Ga8Cu22Nb1；Improve
Ce69Ga8Cu22Nb1The method of bulk metallic glass temperature-room type plasticity deformability is the reduction Ce69Ga8Cu22Nb1Bulk metal
The size of glass.
When institute's diameter is in 1-4mm, the Ce69Ga8Cu22Nb1Bulk metallic glass all shows temperature-room type plasticity deformation energy
Power.And the Ce69Ga8Cu22Nb1The diameter of bulk metallic glass is smaller, and temperature-room type plasticity deformability is higher.
The present invention has the beneficial effect that：
The present invention utilizes the simple method for reducing sample diameter, you can has certain temperature-room type plasticity deformability to obtain
Ce69Ga8Cu22Nb1Bulk metallic glass, and the smaller plasticity of sample diameter is higher, helps to expand its commercial Application.

Embodiment
Technical scheme is described in detail below by embodiment and accompanying drawing.
Following embodiment instrument equipment are as follows：
The bulk metallic glass of embodiment kind different-diameter is made using copper mold water cooling suction casting method, device therefor model
For：WK series non-consumable vacuum arc melting furnaces, thing section photoelectricity, Chinese (Beijing).
The temperature-room type plasticity of bulk metallic glass is measured by compression method obtained by embodiment kind, device therefor model：
MTS809 universal testing machines, China.
Embodiment 1：Different-diameter Ce69Ga8Cu22Nb1The temperature-room type plasticity measurement of bulk metallic glass
Step 1：Ga, Cu and Nb that the Ce and purity for being 98.51wt.% with purity are more than 99.9wt.%, according to chemistry
Formula Ce69Ga8Cu22Nb1Atomic percent alloyage, vacuum arc melting inhale casting stove in, titanium absorption argon atmospher in
Molten alloy, melting number are no less than 4 times, make alloying component uniform.Mother alloy ingot is obtained after cooling.
Step 2：The mother alloy ingot that step 1 is obtained is placed on the water cooled copper mould of argon gas protection and carries out melting, Ran Houli
With the absorbing and casting device in electric arc furnaces, the mother alloy melt after remelting is inhaled using pressure differential and is cast into different-diameter (diameter difference
For 1.5,2,3,4,5,6,8,10mm) cylindrical copper mold in, obtain Ce69Ga8Cu22Nb1Alloy bar material, sample photo are shown in
Fig. 1.
Step 3：Room temperature compression test is carried out to the sample in step 2 using universal testing machine, measures the modeling of its room temperature
Property deformability, as a result as shown in Figure 2, Figure 3, Figure 4.
From the result of embodiment 1 it can be found that the present invention improves temperature-room type plasticity deformability by reducing sample size
Method be fruitful.When the bulk metallic glass diameter is more than 5mm, complete brittle failure behavior is shown；Work as sample
Diameter can show certain plastic deformation ability in below 4mm, and with its plastic deformation ability of the reduction of sample size
Power is stronger.It can be seen that by reducing sample size to improving Ce69Ga8Cu22Nb1This method of temperature-room type plasticity of bulk metallic glass
It is highly effective.
The exemplary embodiment of the present invention is these are only, is not intended to limit the invention, all spirit in the present invention
With all any modification, equivalent and improvement made within principle etc., it should be included in the scope of the protection.
