Technical field
The present invention relates to a kind of titanium/aluminium/magnesium composite plate tooth form faying faces to roll preparation method, belongs to composite metal plate system
Standby field.
Background technique
Magnesium and magnesium alloy are structural metallic materials most light in current engineer application, due to high specific strength, Gao Bigang
Degree, thermal conductivity is excellent, high damping vibration attenuation and the advantages that electromagnetic shielding and excellent reproducibility, it has also become after steel,
The third-largest metal engineering material after aluminum alloy materials is the environment-friendly and energy-efficient structural material for 21 century having development potentiality,
Wide application prospect is showed in auto industry field, aerospace field.However, due to the temperature-room type plasticity of magnesium alloy and resistance to
Corrosive nature is poor, greatlys restrict its development.In addition to magnesium alloy, there are also aluminium alloys and titanium alloy for common light-alloy, wherein
Aluminium and its alloy have many advantages, such as stronger inoxidizability, impact resistance and corrosion resistance, and titanium alloy has intensity height, corrosion resistance
The features such as good, heat resistance height.Therefore, magnesium alloy and aluminium alloy and titanium alloy is compound, titanium alloy can be given full play to and aluminium closes
The advantages that golden high-intensitive and corrosion-resistant advantage, quality of magnesium alloy is light, damping property and electromagnetic shielding performance are good, magnesium is overcome well
It the shortcomings that alloy material poor corrosion resistance, maximizes favourable factors and minimizes unfavourable ones, obtains excellent structure and functional characteristic, widen the application neck of magnesium alloy
Domain.
Mainly there are explosion composite method and roll-bonding method suitable for titanium/aluminium/magnesium composite metal plate preparation method.Explosion is multiple
Close using explosive as the energy, explosive high speed ignition under percussion by different metal large-area welding together with.It is quick-fried
The compound composite plate that can produce various metals is fried, but vibration, noise and the smoke contamination generated that explode can cause shadow to environment
It rings, and production efficiency is lower.Rolling compund is to be rolled metal to be composite using the roll-force of milling train under certain temperature
The features such as system, and then formation metallurgical bonding, have stable product quality good, high production efficiency, simple process, it is easy to accomplish work
Industryization batch production.
However, three kinds of titanium, aluminium, magnesium alloy compound tenses, since the performance of most titanium alloys is substantially better than magnesium alloy and aluminium conjunction
Gold, especially yield strength are very high, and resistance of deformation is very big, the deformation very little of titanium alloy when leading to three's Rolling compund, thus shadow
The composite effect between titanium/aluminium, titanium/magnesium is rung, keeps boundary strength lower.
Summary of the invention
The object of the present invention is to provide a kind of titanium/aluminium/magnesium composite plate tooth form faying faces to roll preparation method, by aluminium alloy
As intermediate layer, make full use of between titanium/aluminium, aluminum/magnesium alloy have good compound ability, preparation have superperformance and
Titanium/aluminium/magnesium composite plate of combination interface intensity.
Technical solution of the present invention is as follows:
A kind of titanium/aluminium/magnesium composite plate tooth form faying face rolling preparation method, using aluminium alloy sheet as middle layer, by titanium
Alloy and magnesium alloy plate rolling are composite plate, the specific steps are as follows:
1) composite surface is cleared up, and the face to be composite of titanium alloy, aluminium alloy and magnesium alloy is coarse to coarse with wire brush polishing
Degree uniformly, with being dried up after alcohol washes buffed surface；
2) the compound tooth-shaped rolling of titanium/aluminium, the face paste combined pressure to be composite of titanium alloy and aluminum alloy plate materials is tight, one after heating
A roller is Rolling compund on the milling train of serrated roller, and titanium/aluminium face to be composite is toothed surface after rolling；The heating of plate when tooth form rolls
Temperature is 450~550 DEG C, and roll preheating temperature is 150 DEG C, and overall reduction is 5~10%；
3) magnesium alloy tooth form rolls, and rolls, rolls on the milling train that a roller is serrated roller after magnesium alloy plate is heated
Face to be composite is toothed surface afterwards；Tooth form is identical as tooth form in step 2), and rolling temperature is 300~400 DEG C, and roll preheating temperature is
150 DEG C, drafts is 5~10%；
4) toothed surface pressing, the toothed surface of titanium/aluminum composite board and the toothed surface alcohol washes of magnesium alloy simultaneously dry up, tooth form
It is pressed after engagement；
5) liner plate Rolling compund is rolled after titanium/aluminium after pressing/magnesium composite plate base heating using the method that liner plate rolls
It makes compound；Rolling temperature is 300~400 DEG C when Rolling compund, and roll preheating temperature is 150 DEG C, and overall reduction is 35~50%；
6) it is straightened trimming, to there is curved rolling composite plate shaping to be straightened, excision composite plate deforms irregular front and back end
Head obtains qualified titanium/aluminium/magnesium composite plate；
The toothed surface pressing of titanium/aluminum composite board and magnesium alloy in step 4) is to carry out at normal temperature, can be on a hydraulic press
To implement, can also implement on milling train, it is ensured that toothed surface generates part and is plastically deformed, and presses two toothed surfaces to be composite sufficiently,
High-temperature oxydation when preventing from heating；
Alignment described in step 6) carries out immediately after Rolling compund, and alignment can carry out on a hydraulic press, can also be more
Roller mill rolling alignment；
The above method be suitable for thicker titanium alloy plate and aluminium alloy, magnesium alloy plate it is compound, if titanium alloy plate
Thickness be less than 5mm, then milling train double roller is serrated roller, titanium/aluminium after Rolling compund when the compound tooth-shaped rolling of titanium/aluminium in step 2)
The two sides of composite plate is toothed surface, Rolling compund after then engaging with the tooth form of magnesium alloy plate face to be composite.
Method is also applied for the rolling of other composite metal plates.
Beneficial effects of the present invention:
1. titanium/aluminium/magnesium composite plate milling method of the present invention is using aluminium alloy as middle layer, first by titanium/aluminium compared with
Then Rolling compund under high-temperature again rolls magnesium and titanium/aluminium under relatively lower temp, realize that titanium/aluminium/magnesium is compound, rolling
It is compound to be easily achieved；
2. rolling plate composite surface for tooth form composite surface, tooth form composite surface engages and is heated and rolled after pressing and is multiple
It closes, not only increases composite contact area, and composite surface in heating process can be effectively prevent to generate oxidation, therefore, composite plate
Interface quality is good, intensity is high.
3. titanium/aluminium/magnesium composite plate has high-strength light, corrosion resistance is good, and heat resistance is high, damping property and electromagnetic shielding performance
Many advantages, such as good.
