Wang, Hao (2006) In-situ Si/Al composite produced by semisolid metal processing. In: ACUN-5 International Composites Conference, 11-14 July 2006, Sydney, Australia.
[Abstract]: Hypereutectic aluminium-silicon alloy can be considered as an in-situ composite with primary silicon acting as the reinforcing phase. In this paper, we use semisolid metal processing technique to produce such in-situ Si/Al composite. Hypereutectic Al-Si alloy, AlSi17Cu5Mg0.55, was cast into a permanent mould with controlled solidification conditions. In the resulted composite, primary Si particles were observed to co-exist with primary Alpha-Al particles, uniformly dispersing in Al-Si eutectic matrix. The structure of the Si particle can be controlled by AlP refinement and thermal refinement, and the Alpha-Al particle can be controlled by semisolid partial remelting.
