Abstract
This present study shows, the effect of applying pressure at rang(10-84) MPa using squeeze casting process to improve the microstructure and actual density of Aluminum alloy A380 was studied.From fig(5) its clear that the microstructure of prepare casting samples consists of two phases of hard eutectic (Al-Si) and Primary α-Al. The effect of applying pressure leads to increase the surface fraction percentage of eutectic phase at (68-84) MPa, but the eutectic percentage was decreased at the same range the actual density was increased at (10,17,84) MP.
