Notes:
Microstructural evolution of the spray atomized and powder thixoformed hyper-eutecticA390 aluminum alloy was investigated. The spray atomized powder revealed homogeneous andvery fine silicon particles distribution, due to the rapid solidification of the alloy. The semi-solidpowders were extruded into a closed die cavity through a hole for the plastic deformation of thepowder particles. A drop forge of 45kg weight at different heights was used in this investigation.Remarkable rearrangement and growth of the silicon rich phase was revealed in the final stage
