That is, according to method (2) above, the manufacturing process becomes complicated because the Al alloy needs to be powdered and a molding device is required, which increases the manufacturing cost of the composite material. Its uses are limited.

However, there are problems in that the plating process increases production costs and that the Al alloy composition is specified and lacks versatility.

In producing l-alloy composite materials, ceramic particles are introduced into the molten metal while mechanically convecting Al or Al alloy molten metal, and shearing force is applied to the molten metal during the convection to cause wetting of the particles and the molten metal. This is a method for producing an Al or Al alloy composite material, the key point of which is improving the properties and uniformly mixing the material.

The wettability between the molten metal and ceramic particles can be improved, and the Al alloy can be made by directly mixing the ceramic particles into the molten metal without performing the conventional plating treatment on the particle surface or changing the Al alloy composition. A composite material could be manufactured. That is, by applying a strong shearing force to the molten metal, the collision force of the molten metal against the cera main ivy particles was increased, thereby increasing the wettability between the ceramic particles and the molten metal.

拌軸６の挿入深さを設定した。After melting 1500 g of 2024Al alloy as a matrix in a crucible 1 in the apparatus of the present invention provided in a nichrome wire electric furnace (not shown), it was maintained at 700°C. After the melting and holding is completed, the cylindrical partition wall 2 held by the partition wall holder 5 is inserted into the crucible 1, and a propeller 4 is installed to apply propulsive force to the molten metal 11 to cause convection, and a shear is applied to the convecting molten metal. A stirring shaft 6 equipped with a rotor 3 for applying force was inserted into the partition wall 2. The stirring shaft 6 was connected to a stirrer (not shown) outside the furnace, and was configured to rotate within a range of 10 to 1500 rpm. Further, the propeller 4 and the rotor 3 are both located between the lower end of the partition wall 2 and the lower end of the corresponding through hole 10 for introducing the molten metal into the partition wall 2, and the insertion depth of the stirring shaft 6 is It was set.

した。After inserting and positioning the stirring shaft 6 to which the propeller 4 and rotor 3 were attached, rotation of the stirring shaft 6 was started. The rotational speed at this time was set to 500 rpm from the viewpoint of the minimum value necessary for convection of the molten Al alloy in the crucible 1.

Particles were intermittently introduced into the partition wall 2 at a rate of 10 g, and the final amount introduced was 500 g. Note that the SiC particles introduced at this time had been preheated at 700° C. for 30 minutes.

迄に１０分を要した。In addition, the procedure for introducing SiC particles was such that after the previously introduced SiC particles were completely engulfed in the molten metal, the next 10 g of SiC particles were sequentially introduced to prevent SiC particles from accumulating on the surface of the molten metal for a long time. It took 10 minutes until the entire amount of SiC was added.

中に大気が巻込まれることがあるので、粒子の投入量に
応じて攪拌軸６の回転速度を徐々に高める必要がある。The viscosity of the molten metal 11 increases as the amount of SiC particles introduced increases, and the fluidity tends to deteriorate, making it difficult to generate convection.Therefore, as the total amount of SiC particles added increases, the rotation of the stirring shaft 6 increases. The speed was increased and the propulsive force given to the molten metal 11 was increased. However, if the rotation speed is increased too much, a vortex will be formed between the molten metal 11 and the stirring shaft 6, causing the molten metal 11 to
Since the atmosphere may be drawn into the mixer, it is necessary to gradually increase the rotational speed of the stirring shaft 6 depending on the amount of particles added.

was set, and the inside of the chamber was degassed via the degassing vibrator 9 to create a vacuum atmosphere of 10-'' Torr.At the same time as the degassing, the rotation speed of the stirring shaft 6 was increased to 1500 rpm.
Convection and stirring were continued for 15 minutes. At this time, Si
The air that has been somewhat trapped in the molten metal 11 along with the C particles is removed from the system, while the particles trapped in the molten metal 11 repeat convection within the crucible 1, causing the rotor 3 and the partition wall 2 to flow together. The molten metal 11 is uniformly dispersed within the molten metal 11 by receiving a shearing force therebetween.
