Description
Technical field
The invention belongs to a kind of aluminum alloy materials, are exactly a kind of preparation methods of aluminum copper alloy material.
Background technology
The material of vacuum forming mould main body mostly uses ZL401 alloy materials at present, and ZL401 is to belong to the conjunction of Al-Zn systems
Gold, because the content of zinc in alloy is more, therefore density is larger, and corrosion resistance is poor, and castability is poor, is embodied in hot cracking tendency
Greatly, poor fluidity, therefore sand holes, stomata, shrinkage defect, and these defects occur in the material during casting and use
It is that could find after processing, very big negative effect is brought to processing cost and manufacturing cycle, we combines ZL401 material
Characteristic and its composition is analyzed, by changing material composition, develops this material of aluminium copper, and by heat at
Reason carries out tissue change to material, reaches elimination defect, increases the mechanical performance of material, and improves the surface roughness of material.
Because copper has larger solid solubility in aluminium, and change with temperature and change, therefore in aluminum copper alloy material, drop
The content of low zinc, increase the content of copper, mechanical strength is improved by solution strengthening and ageing strengthening；Add in aluminum copper alloy material
Machinability can be improved by entering magnesium, while addition copper and magnesium can form hardening constituent in aluminium, and reinforcing can be played in timeliness
Effect；In addition, the effect of significant crystal grain refinement can be obtained by adding appropriate titanium, so that aluminum copper alloy material acquisition is better
Performance.
The content of the invention
The defects of it is an object of the invention to for existing aluminum alloy materials, provided to people a kind of with higher strong
Degree, excellent plasticity, good mobility and the aluminium copper material with good heat-treatability, machinability and polishability
The preparation technology of material.
For achieving the above object, the present invention adopts the following technical scheme that：
Aluminum copper alloy material prepared by the present invention is characterized in that：Component containing following percentage by weight meter：Copper
1%~4%, titanium 2%-5%, iron 0.1~1.5%, silicon 0.2~1.5%, rare earth ＜ 1%, remaining is aluminium；The rare earth element
For at least one of lanthanum, cerium, neodymium and yttrium.
The present invention comprises the steps：
(1) cast：
A, specification is loaded into stone at room temperature for fine aluminium, the aluminum titanium alloy of aluminum content >=99% by the parts by weight of said components
Melting in black crucible electrical resistance furnace, copper continuation melting is added according to above-mentioned mass ratio when temperature rises to 720 DEG C；
B, rare earth, iron and silicon will be added when smelting temperature rises to 720~740 DEG C in above-mentioned graphite crucible resistance furnace, 6~
Solution in stove is stirred after 10min and poured into the good sand mold of pre-production, it is standby that casting is made through cooling, knockout, cleaning
With；
(2) it is heat-treated：
A, above-mentioned casting is cut into bar blocks；
B, it is through room temperature water quenching, cold after being heated 8 hours in 520~530 DEG C of resistance furnace bar blocks casting to be put into temperature
But, place into resistance furnace be heated to 300~370 DEG C be incubated 4~8 hours, come out of the stove and produce aluminum copper alloy material.
The content of titanium is 60wt% in the titanium-aluminium alloy.
The effect of the present invention
1st, because copper has larger solid solubility in aluminium, and change with temperature and change, it is strong by solution strengthening and timeliness
Change improve mechanical strength, therefore make the present invention aluminum copper alloy material and meanwhile have higher intensity, excellent plasticity, well
Mobility, the defects of sand holes, stomata, shrinkage porosite are less prone to after casting.
2nd, there is good heat-treatability because certain combination energy between copper atom and room be present, i.e., copper atom with
Room is combined together, and room is stably in solid solution, is not easy to migrate to defect area.
3rd, there is good machinability, magnesium alloy has excellent machinability, and its cutting speed is significantly high
In other metals, the hardness of aluminium copper is lower than steel, more conducively machining, and the abrasion to cutter is small.
4th, there is good polishability, appropriate titanium is added into aluminium and its alloy can obtain the effect of significant crystal grain refinement
Fruit, after aluminum casting is repaired by machining and surface pincers worker, rough polishing is carried out to surface and essence is thrown, the effect of minute surface can be reached.
