Definitions

  • the present disclosure relates to the technical field of aluminum alloys, in particular to a method for preparation of an aluminum matrix composite.
  • the 6061 aluminum alloy is one of the most widely applied Al—Mg—Si wrought aluminum alloys. Due to its relatively good mechanical properties, excellent corrosion resistance and good weldability and molding performance, the 6061 aluminum alloy is broadly applied to the automobile industry. With the rapid development of the automobile industry, more and more vehicle parts are made of the 6061 aluminum alloy. In the meantime, issues such as energy supply shortage and severe exhaust pollution caused by the automobile industry are becoming worse. In particular, under the strict limitations of automobile energy efficiency standards in all countries, energy conservation, environmental protection, higher driving safety and higher driving comfort become critical challenges that automobile manufacturers have to face. Given the above Situation, lightweight technology is being applied to all parts of an automobile.
  • the particle enhanced aluminum matrix composite has considerable application potentials in the field of automobile parts due to its low density, high specific stiffness, high specific strength, low expansion, high heat conduction and other features.
  • TiB 2 particle enhanced aluminum matrix composite In an existing in-situ synthesis technology, the method for the preparation of the TiB 2 particle enhanced aluminum matrix composite by reactions between KBF 4 and K 2 TiF 6 mixed salt and an aluminum melt is simple in process and low in cost, thereby having good industrial prospects.
  • TiB 2 enhancing particles have a large size (about 1 ⁇ m), and on the other hand, TiB 2 particles may suffer a severe aggregation phenomenon. Those are the problems having to be settled urgently in the process of the preparation of the in-situ synthesis aluminum matrix composite.
  • the present disclosure aims to provide a method for preparation of an aluminum matrix composite.
  • the aluminum matrix composite prepared by the method contains TiB 2 particles fine in size and uniform in distribution.
  • the mixed powder is dried at 200-250° C. for 2-3 h.
  • an atomic ratio of Ti to B in the K 2 TiF 6 powder and the KBF 4 powder is preferably 1:2, and an addition amount of the reaction auxiliary Na 3 AlF 6 powder is 10-20% of the total mass of the reaction salt K 2 TiF 6 and the reaction salt KBF 4 .
  • the speed of the mechanical agitation is 250-350 r/min, and the time for the mechanical agitation is 3-5 min.
  • the speed of the mechanical agitation speed is 250-350 r/min.
  • the pouring temperature is in the range of 705-710° C.

  • the method of the present disclosure is simple in process, low in cost and beneficial for mass production, and the composite prepared by the method of the present disclosure contains TiB 2 enhancing particles fine in size and uniform in distribution and may remarkably improve mechanical performance indicators of a matrix alloy.
  • the method for preparation of the aluminum matrix composite includes the following steps:
  • the method of the present disclosure adopts an industrial common mixer to evenly mix reaction salts, thereby being higher in efficiency and safety, simple in process and beneficial for mass industrial production.
  • the step S 1 of adding the reaction auxiliary Na 3 AlF 6 to the mixed salt accelerates the reaction rate of the mixed salt and the aluminum melt and shortens the reaction time.
  • the step S 4 of scattering the mixed salt onto the surface of the melt by the powder sprayer on one hand, the contact between the mixed salt and the surface of the melt is more uniform, and compared with the means of sintering the mixed salt into cakes and adding the cakes in to the melt, the method of the present disclosure is simpler and more economical and meanwhile reduces the tendency of particle aggregation; and on the other hand, the mixed salt may react with the melt uniformly and rapidly, and thereby avoiding the severe change within a short time of the temperature of the melt during addition of a large amount of the reaction salts.
  • the step S 5 of performing agitation on the melt may effectively disperse TiB 2 particles generated during in-situ synthesis, thereby avoiding particle aggregation and sedimentation.
  • step S 8 of performing ultrasonic treatment on the melt on one hand, blocky aggregation of TiB 2 particles is effectively cracked by an ultrasonic cavitation effect; and on the other hand, TiB 2 particles and alloy elements are more uniformly distributed by an ultrasonic acoustic streaming effect.
  • the method of the present disclosure omits procedures of ball-milling of the mixed salt, cold pressing into cakes and sintering in a mixed salt reaction method and thus improves material preparation efficiency and saves production cost. Meanwhile, firstly, a TiB 2 enhanced pure aluminum master alloy material is prepared, and then the TiB 2 enhanced 6061 aluminum alloy composite is prepared according to the method for the preparation of alloy elements as desired. This method avoids element burning loss in a direct high-temperature reaction process of the mixed salt and the 6061 aluminum alloy, and the aluminum matrix composite of different matrix compositions may be prepared as desired from the TiB 2 particle enhanced pure aluminum master alloy.
  • the method for preparation of the aluminum matrix composite of the present disclosure includes the following steps:

  • step (III) immersing the compound powder sintered round billet in the step (I) into the melt in the step (II) until the billet is completely molten, controlling the reaction temperature to be 850° C., and maintaining the temperature for 30 min while not performing agitation;
  • step (V) sequentially adding alloys of AlSi20, AlCr10, AlMn10, AlTi20, pure Cu, pure Zn and pure Mg to the melt in the step (IV) according to the standard composition of the 6061 aluminum alloy while maintaining the melt temperature not higher than 760° C., and maintaining the temperature at 750° C. to completely melt the alloys;
  • step (VI) evenly scattering a slag-cleaning agent onto the surface of the melt in the step (V) by a powder sprayer, introducing high-purity argon with a flow rate of 3 L/h, performing mechanical agitation at a revolution speed of 300 r/min, stirring and degassing for 5 min, and then stripping off scum on the surface; and
