Abstract: Extrusion process of a large diameter thin-walled aluminum profile was simulated by Arbitrary Lagrangian Eulerian (ALE) algorithm based on HyperXtrude software. The results show that the material flow velocity in the bearing exit of the initial design die is non-uniform. Three times modifications were performed and simulated. The optimal design with more uniform flow velocity in the bearing exit was obtained.

Abstract: The zinc alloy samples were prepared under the condition of the vibration and ordinary pressure, 0.4Mpa pressure and 0.7Mpa pressure. The photos of the microstructure morphology were obtained by optical microscopy. The analysis result shows that the crystalline microstructure of solidification by the band edge changes from dendrite-shaped to oval, spherical grains. The internal grains havealso been refined.
