The invention discloses a kind of rotary pressure deformation preparation methods of particle enhanced aluminum-based composite material tubing, belong to metal-base composites processing technique field.Composite material pipe is prepared through hot spinning cogging, warm spinning finished product in the spinning blank prepared using powder metallurgic method, and the deformation temperature of the hot spinning cogging is 290 450 DEG C, and spinning pass is 5 passages, and between every spinning pass, carries out online annealing processing.Two spinning pass deflections are smaller before this method, ensure that blank inner surface does not crack；Line annealing process is used between spinning pass, eliminates processing hardening.The present invention uses particle enhanced aluminum-based composite material large diameter thin wall pipe prepared by spin-on process, is widely used in aerospace aircraft.
Description
Technical field
The invention belongs to metal-matrix composite pipes processing technique fields, and in particular to a kind of particle reinforced aluminium-based compound
The rotary pressure deformation preparation method of material pipe.
Background technology
Certain naval vessel of the country uses aluminium alloy or steel making more with tubing at present, and existing main problem is aluminium alloy rigidity
It is low, and steel part then increases the weight of cylinder, seriously constrains use of the product under complex environment (such as seawater).Particle
Reinforced aluminum matrix composites have many advantages, such as that specific density is small, specific stiffness is high, specific strength is high, and Abroad in Recent Years mostly uses aluminum-base composite
The material manufacture tubing, and it is domestic at present still without carrying out relevant work, it constrains product of changing products and further upgrades.
Shear spinning technique is to make feed motion by spinning roller, stresses on the metal base rotated along same axis with core model
Material makes it generate continuous local plastic deformation and become required hollow revolving parts.Spinning processing method is commonly used to
Process large size, thin walled cylindrical member.
Invention content
The present invention is poor for particle enhanced aluminum-based composite material hot isostatic pressing blank plasticity, when deformation problem easy to crack,
A kind of rotary pressure deformation preparation method of particle enhanced aluminum-based composite material is provided, it is quiet through cold pressing, heat etc. after raw material powder mixing
Pressure processing is prepared into spinning blank, which is characterized in that the direct hot spinning cogging of spinning blank prepared by hot isostatic pressing.
The matrix of the spinning blank is aluminium alloy；Reinforced particulate is one in silicon, diamond, silicon carbide, silicon nitride
Kind or more than one, the volume fraction of reinforced particulate is less than 40%；The plasticity 5-8% of spinning blank.
The temperature of hot spinning cogging deformed area is 150 DEG C -450 DEG C.
The spinning pass of the hot spinning cogging is 5 passages, feed speed 70-100mm/min, blank outer surface linear speed
Spend 19-21m/min；Wherein, the reduction 10-20% of the 1st passage, deformed area temperature are 370-450 DEG C；2nd passage is thinned

Between the hot spinning cogging is per spinning pass, online annealing processing, annealing process are carried out：Extremely by blank heating
450 DEG C -500 DEG C, rotary pressure deformation area temperature is naturally cooled to, starts lower a time spinning.
Advantages of the present invention is：
(1) rotary pressure deformation process is highly sensitive to temperature, the present invention considered when considering rotary pressure deformation heating temperature as
Lower factor：(a) blank heating temperature is measured using surface thermometer or infrared radiation thermometer, and the temperature surveyed is the temperature of workpiece surface
Degree, has any different with the deformation temperature in blank whole deformation area；(b) when rotary pressure deformation, workpiece and core model, between spinning roller and workpiece
There are larger frictional force to cause deformed area temperature to have certain rising since mutual friction will produce a large amount of frictional heat；
(c) rotary pressure deformation belongs to aximal deformation value high-speed deformation, easily generates insulating band in deformed area, causes deformed area temperature to have certain upper
It rises.
(2) the spinning blank described in this method is prepared using hot isostatic pressing, and plasticity is poor, preceding two spinning pass deformation
Amount is smaller, ensures that blank inner surface does not crack, after two passage rotary pressure deformations, distribution of particles, interface cohesion in blank,
Matrix etc. all has some improvement, and plastic deformation ability is improved, and follow-up rotary pressure deformation amount is larger.
(3) hot spinning deformation process is the process of Dynamic softening and dynamic hardening interaction, particle reinforced aluminium-based compound
Due to the presence of reinforcement particle, work hardening rate greatly improves material, used between this method spinning pass line annealing process with
Eliminate processing hardening.
