FRICTION STIR MECHANICAL SINTERING DEVICE AND FRICTION STIR MECHANICAL SINTERING METHOD

摘要

A friction stir mechanical sintering device according to the present invention comprises: a lower mold which has a mold cavity formed therein with a powder material; and a press forming part which is provided to move vertically from an upper portion of the lower mold to the inside of the mold cavity and to rotate, pressurizes the powder material, and applies frictional heat to friction-stir and sinter the powder material. According to the friction stir mechanical sintering device and the friction stir mechanical sintering method of the present invention, the press forming part moves vertically and rotates to pressurize the powder material and to apply frictional heat. Therefore, the plastic flow is induced by sintering and friction stir and a molding object having a compact microstructure can be manufactured with a simple structure. In addition, compression molding and sintering can be performed in one mold, thereby improving processing efficiency. Further, the pressure forming part pressurizes and rotates by being in contact with one side of the molding object to mold the molding object having tissues denser toward both sides from the center of the molding object, thereby easily manufacturing the molding object to induce breakage in the center.;COPYRIGHT KIPO 2019
