Abstract
Investigation on the extrusion of rapidly solidified Al-Si alloys was performed in order to develop an inexpensive production process of high strength parts. It is necessary to establish optimum process variables for the extruding condition through the experiments, because it is high cost and time consuming process. In this paper, the experimental results was compared to the finite element analysis for the extrusion of rapidly solidified Al-Si alloys. The results of this simulation helped to understand the distribution of relative density and effective stress for rapidly solidified Al-Si alloys during the extrusion process. This information is expected to assist in improving the extrusion operations of rapidly solidified Al-Si alloys.
