Simulation Analysis of Metal Flow during Extending Extrusion Semisolid AA2017 Alloy

摘要：

　　Extending extrusion process of semisolid AA2017 alloy was achieved.Metal flow during the process was analyzed by the finite element simulation.It was shown that alloy flow velocity decreases gradually from the center part to the sides of the mould,sometimes a transitional turbulence region appears in the middle.A smaller declining angle θ and without step d is suggested in the design mould.Alloy flow velocity at the center of the forming region decreases linearly with increases of the extending ratio s1/s0.
