金属の凹設部に的確に埋設することが可能となる。The present invention involves heating the base metal and the SiC whisker-reinforced composite material to 450 to 550°C during pressure forging, and preheating the forging pressure head to 200 to 400°C, and
By forging at a pressure of 0.00 to 3000 kg/cm', it is possible to embed the material accurately in the recess. Base metal and 8iC Wiss force-reinforced composite to 450
Heating to ~550°C facilitates plastic deformation of the SiC whisker-reinforced composite, allowing it to be properly embedded in the recess. In this case, it is necessary to preheat the forging pressure head as well, and it is possible to prevent a local temperature drop from occurring during pressure forging. Furthermore, in order to smoothly progress the plastic deformation of the SiC whisker-reinforced composite material, the pressure during forging was increased to I.
