(Problem to be Solved by the Invention) However, since the solidification and forming temperature of the aluminum alloy matrix composite material is relatively low, the capsule made of mild steel does not soften sufficiently during forming, causing non-uniform shrinkage. As a result, when cutting a cylindrical product, which is often used as an extrusion material, for example, there is a problem that the effective diameter becomes small and the yield becomes extremely low.

In this case, in order to increase the yield, it is sufficient to prevent uneven shrinkage and increase the powder filling rate in the capsule. For this reason, filling is performed under pressure using a press to improve the filling rate. However, increasing the filling rate causes the problem that degassing becomes difficult. Therefore, the filling rate cannot be increased very much, and the filling rate is limited to about 60 to 70%. Therefore, even when pressure-filled, uneven shrinkage of the capsules is unavoidable, and the current yield is as low as about 65%. Figures 4 and 5 schematically show the shape of a pressurized cylindrical capsule made of mild steel after HIP, and as shown in the figure, considerable uneven shrinkage occurs even when pressurized. do.

When solidifying and molding an aluminum matrix composite material, it is usually hot-formed, and at this time, the aluminum capsule is sufficiently softened compared to the mild steel capsule and has sufficiently high ductility, so that it is uniformly deformed. In addition, the material inside the capsule is also softened because the matrix is aluminum or aluminum alloy, so when conventional mild steel capsules are used, there is a large difference between the deformation resistance of the inside material of the capsule at high temperatures and that of the capsule. However, by using an aluminum capsule, the deformation resistance at high temperatures is close to that of the material inside the capsule, so it shrinks uniformly.

(Effects of the Invention) According to the present invention, since the material of the capsule is made of aluminum or its alloy, the capsule can be sufficiently softened even at a relatively low HIP molding temperature such as with an aluminum alloy matrix composite material, and can be used as a mixed powder. Since the strength is about the same, shrinkage in the radial and axial directions can be made uniform, and the yield when machining cylindrical products is approximately 95%.
The cost of the product, the aluminum matrix composite material, can be reduced. Furthermore, since the capsule contracts uniformly, it becomes possible to design the capsule shape in accordance with the required size and shape of the solidified molded product, increasing the degree of freedom of the manufactured solidified molded product.

This made it easier to degas the capsule.
