Aluminum 7075 alloy extrusion billets have been used as the feedstock for thixoforging of thin plates. Recrystallisation and remelting (RAP) route has been employed to prepare the semisolid slurries. A direct die-filling system was designed for thixoforging of thin plate. Thin plates were thixoforged at the temperatures of 610℃, 615℃ and 620℃ with application of 70 MPa forging pressure. The quality of thin plates was examined by X-ray radiography. Hot tearing defects were detected when thixoforging was conducted at higher temperatures. The elongated grains in the initial extrusion billets were transferred to the globular grains within the semisolid slurry. However, some interconnected grains were observed. The microstructure of thixoforged thin plates indicated that a disagglomeration effect was active during thixoforging.
