摘要

Horizontal continuous casting (HCC) Al-12%Si alloy billets were prepared using fine-grained Al-12%Si as a raw material. The influence of this fine-grained raw material on the microstructure and tensile proper- ties was studied. The uniformity of the HCC Al-12%Si alloy billets was also analyzed. The results show that the fine-grained raw material can effectively reduce macrosegregation and make both the χ-Al and eutectic silicon much finer. The ultimate tensile strength and elongation clearly increased with an addition of 30% fine-grained raw material compared to the HCC alloy billets with no addition of fine- grained raw material. However a small decrease nonetheless occurred after an addition of fine-grained raw material up to 50%.
