The microstructures and thermal stabilities of high silicon aluminum alloys prepared by spray deposition (SD) and subsequent heat treatment were studied. The results indicate that the size of the primary silicon in the deposited ingots is much smaller than that prepared by normal casting. After the subsequent heat treatment, the pores in deposited ingots are disappeared and their density increase to about 100%. While the size and volume fraction of the primary silicon in solidified hypereutectic Al-Si alloy increase with the increasing of silicon content, the corresponding thermal expansion coefficient decreases.
