Description
Technical field
The present invention relates to a kind of Cu70Zr20Ti10/ Cu non-crystaline amorphous metal sheet composite powder and its preparation technology.
Background technology
Cu base bulk metallic glass has performances such as excellent physics, chemistry, mechanics, but its brittleness at room temperature and low leads
Conductance hot property limits its commercial Application, and composite can solve these problems.Powder metallurgic method is to prepare bulk amorphous alloy
One of technology of alloy composite materials, the preparation of high-quality non-crystaline amorphous metal composite powder are that the primary key in powder metallurgic method is asked
Topic.Composite powder has artificial composite powder and two class of spontaneous composite powder, and the former is difficult to mix and powder due to various powders
There is Problem of Wettability between end and be restricted, the latter is separated out in powdered base due to spontaneous Crystallization Phases, can be with powdered base
Organically combine.Cu70Zr20Ti10The amorphous formation ability of alloy is poor, how to prepare non-crystaline amorphous metal composite powder be one important
Problem.
Content of the invention
It is an object of the invention to provide a kind of Cu70Zr20Ti10/ Cu non-crystaline amorphous metal sheet composite powder and its preparation work
Skill.
The purpose of the present invention is achieved through the following technical solutions：A kind of Cu70Zr20Ti10/ Cu non-crystaline amorphous metal sheet is multiple
Close powder, it is characterised in that：Spherical Cu is made by ball milling70Zr20Ti10The continuous flaking of crystal alloy powder, by mechanical milling process
The heat of middle generation raises ball milling system temperature so that sheet Cu70Zr20Ti10Copper in alloy powder is separated out, so as to
Obtain by Cu crystal grain distribution in Cu70Zr20Ti10Non-crystaline amorphous metal composite powder in sheet non-crystaline amorphous metal matrix.
Above-mentioned Cu70Zr20Ti10The preparation technology of/Cu non-crystaline amorphous metal sheet composite powder, comprises the steps:（1）Will be pure
Block Cu, Zr and the Ti spent for 99.95wt% is Cu by at%70Zr20Ti10Composition proportion dispensing, the material for preparing is put into vacuum
In the crucible of intermediate frequency furnace, melting forms foundry alloy；（2）Foundry alloy is atomized by globulate crystal alloy powder using atomization；
（3）Powder is put in stainless steel jar mill, is poured absolute ethyl alcohol into and ball grinder is full of；（4）It is 500r/min in ball milling speed
Under conditions of after ball milling 70h, you can obtain sheet non-crystaline amorphous metal composite powder.
The product that the present invention makes uses X-ray diffractometer respectively（XRD）The detection non-crystallization degree of powder and Crystallization Phases
Species, use SEM（SEM）Detect the form of powder, use transmission electron microscope（TEM）The distribution shape of detection Cu
Condition, find the product made of the present invention be by spontaneous Cu crystal grain distribution in Cu70Zr20Ti10Formed in sheet non-crystaline amorphous metal matrix
Non-crystaline amorphous metal composite powder.
Cu of the present invention70Zr20Ti10/ Cu non-crystaline amorphous metal sheet composite powder is a kind of spontaneous composite powder, its preparation technology
Advantage with the simple and low cost of equipment.
Specific embodiment
Below according to specific embodiment, the invention will be further described.
Embodiment
Copper 1976.5475 ± 0.0001g, zirconium 810.6999 ± 0.0001g and titanium are weighed in batches with assay balance
212.7527 ± 0.0001g, is put in the copper crucible of intermediate frequency furnace, is evacuated to 10-3Pa, being filled with argon gas makes the pressure of vacuum chamber
Power reaches 0.7 atmospheric pressure, and then molten alloy obtains foundry alloy, then above-mentioned foundry alloy is atomized globulate crystal alloy powder
End, is put into powder in stainless steel jar mill, adds absolute ethyl alcohol to be completely filled with ball grinder, is put in rotational speed of ball-mill on ball mill
Take out after ball milling 70h under the conditions of 500r/min, obtain Cu70Zr20Ti10/ Cu non-crystaline amorphous metal sheet composite powder.
