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