摘要：

Thin plates (150 x 150 x 1.2 mm) with embedded corrugation are fabricated using semisolid forming. The die cavity used in the forming is designed using fluid analysis. A semisolid slurry is prepared by a cooling with EMS and heating process. The slurry is then injected into a forging die attached to a 200 tonf hydraulic press. Subsequently, the slurry is compressed by a punch, flown into the die cavity, and then solidified. A356 (cast Al alloy) and AA6061, AA2024, and AA7075 (wrought Al alloys) are used.
