is filled so as to surround the core shaft 3. The aluminum-based rapidly solidified powder used in this example was manufactured by the atomization method, and its rapid solidification rate was 104 to 106°C/se.
After filling the powder 10, the stem platen is pressed down, and the powder 10 is extruded from between the inner periphery of the extrusion port 11 of the die body 6 and the outer periphery of the core shaft 3, and the imaginary line in the figure The pipe is designated as pipe 7 as shown in . Here, the extrusion temperature was 480°C, and the extrusion ratio was 40-50.
