Abstract
The effect of cyclic pressure on the thermal and microstructural behaviour of the A356 alloy and the addition of commercial Al-Sr Master Alloy, Nano Alumina Master Alloy and a combination of both Master Alloys during the squeeze casting was investigated in this study. The results show that the α-dendrite growth temperature was increased and the Al-Si eutectic growth temperature was decreased substantially, resulting in a super refined, as-cast, equiaxed α-Al cells and ultra fine dendritic eutectic Si in the modified and unmodified A356 aluminum alloy. Moreover, very rapid spheroidization of the Si particles was observed within a very short Solution Treatment time (15min) of the squeeze cast unmodified and Sr modified A356 alloy. It is expected that the results of this study will lead to a number of further fundamental and applied research rendering new alloys and technology.
