Description
Technical field
The present invention relates to the connection of composite, refer in particular under the semisolid condition particle enhanced aluminum-based composite material is carried out the method and apparatus that moment loads and realization connects.
Background technology
Particle enhanced aluminum-based composite material has become an important focus in the current field of research of metal owing to specific strength height, good combination property are considered at present one of the most competitive metal-base composites.Wherein, the SiC particle enhanced aluminum-based composite material is with fastest developing speed in various composites.Because the both macro and micro structure of particle enhanced aluminum-based composite material complexity, make their connection than single homogeneous material complexity many, limited the application of particulate reinforced composite in a lot of fields to a certain extent, the connection of particle enhanced aluminum-based composite material has become one of focus of current this area research both at home and abroad.
From existing result of study, the connection of SiC particle enhanced aluminum-based composite material mainly comprises melting, soldering and diffusion welding (DW) three major types.In order to improve the intensity of jointing, improve the syndeton quality, the researcher has also proposed many novel aluminum matrix composite interconnection techniques, mainly comprises friction stir welding, pulse laser welding, flash butt welding and plasma spraying etc.Research and analyse from existing, the interconnection technique of particle enhanced aluminum-based composite material should possess several like this conditions: 1) can form good jointing, interfacial reaction is few; 2) must effectively avoid the oxidation of alloy matrix aluminum; 3) reduce the jointing place as far as possible strengthen the poly-partially of particle; 4) simple to operate, avoid using admixture as far as possible.Existing various particle enhanced aluminum-based composite material interconnection techniques are analyzed, found that they all have certain effect for connecting the SiC particle enhanced aluminum-based composite material, but all exist various deficiencies and problem to some extent.The subject matter that melting exists is that the wild phase particle is easily and the aluminum matrix alloy generation frangible compounds that reacts in the high-temperature soldering molten bath; Molten bath viscosity height, mobile poor has increased the sensitiveness to defectives such as pore, incomplete fusions; It is poly-partially that the wild phase particle takes place during weld pool solidifies, influences the performance of joint.In the brazing process, liquid solder is poor to the wetability of SiC, the weak connection ratio of bonding pad is higher.The liquid phase diffusion connects the intermediate layer alloy that needs exploitation special, and can not control the fusing of aluminum matrix alloy at present completely effectively and strengthen the poly-partially of particle.Simultaneously, no intermediate layer liquid phase diffusion connection is still needed further perfect as a kind of new method.In friction stir welding, because the effect of stirring body, redistribution has taken place in the SiC particle, has formed the poly-partially phenomenon that strengthens particle at connector area.In the pulse laser welding process, because laser pulse local heat temperature height, make that to strengthen between particle and the matrix chemical reaction violent, formed frangible compounds, reduced the intensity of joint.The flash of light later stage of flash of light built-up welding has formed one deck liquid level in the joint end, and this liquid level is extruded under pressure, makes the enhancing distribution of particles of joint that variation take place.And the subject matter of plasma spraying is to need to select suitable dusty spray, and joint efficiency also has much room for improvement simultaneously.Therefore, development of new particle enhanced aluminum-based composite material interconnection technique has the meaning of particular importance.
Semisolid characteristic research to the SiC particle enhanced aluminum-based composite material shows that under certain holding temperature, temperature retention time and forming pressure, the semi-solid rheological performance of SiC particle enhanced aluminum-based composite material is better than matrix alloy.The rule of particle enhanced aluminum-based composite material semi-solid rheological performance, semi-solid-state shaping to reality has important directive significance: at technological parameter one regularly, can suitably improve SiC grain volume fraction in the composite, to obtain good semi-solid rheological performance and crystallized ability; Also can select technological parameter with the Changing Pattern of temperature, time and pressure according to the semi-solid rheological performance of composite.Desire to make composite to have semi-solid rheological performance preferably, by selecting higher forming pressure, higher semisolid holding temperature and the temperature retention time of growing, can make particle enhanced aluminum-based composite material have rheological behavior preferably, thereby guarantee good crystallized ability.The report and the patent application that also do not utilize at present the semisolid characteristic of SiC particle enhanced aluminum-based composite material to connect.
Summary of the invention
The present invention proposes a kind of semisolid state joining method and device of particle enhanced aluminum-based composite material, to overcome above-mentioned drawback.
A kind of semisolid state joining method of particle enhanced aluminum-based composite material, it is characterized in that: the particle enhanced aluminum-based composite material masterbatch is fixing side by side, adopt resistance heated or induction heating mode composite to be heated in the liquid-solid two-phase humidity province of aluminum matrix alloy near the liquidus temperature, the width that the width that heats on composite loaded than moment is wide slightly, to guarantee to load the uniformity of thixotropic flow in the zone, immediately the particle enhanced aluminum-based composite material through heating is carried out the moment loading, promptly joint face is rolled with a moving runner of exerting pressure, utilization is in the thixotropy that particulate reinforced composite had under the semisolid condition, make particle enhanced aluminum-based composite material generation thixotropic flow, thereby realize the connection of particle enhanced aluminum-based composite material.
Connect the translational speed of pressure head by speed regulator control rolling, thereby control heat time heating time and connection speed, regulate the connection pressure head that rolls to the particle enhanced aluminum-based composite material applied pressure by pressue device.
A kind of semisolid jockey of particle enhanced aluminum-based composite material, form by add in-place thermic devices, temperature thermocouple, temperature controller, rolling connection pressure head and speed regulator, wherein, add in-place thermic devices, temperature thermocouple and rolling are connected pressure head and are arranged in sequentially on the guide rod that is parallel to joint face, and under the driving of motor, move with the connection pressure head that rolls, temperature controller is connected with temperature thermocouple by lead-in wire, and speed regulator is connected pressure head with rolling and connects; Adjustable pressue device is installed in and roll connects on the pressure head, in the jockey both sides, be provided with fixedly connected mother metal anchor clamps, be limited in substantially within the loading scope with the thixotropic flow that guarantees particle enhanced aluminum-based composite material in connection procedure.
