Interactions of Melt Processes of Hypoeutectic Al-Si Alloys

In this paper, the interactions among raw material states, modification and refinement in melt processes of hypoeutectic Al-Si cast alloys are summarized. On the basis of the above, It's pointed out that understanding and controlling the transition processes from charge materials to melt then to product is the key to improve the properties of casting aluminum alloys, and that determination of reasonable melt processes should consider synthetically the inheridity of raw materials and various melt processes, as well as their interactions.
