and the elongation is improved from 0.35% to 0.48%. Key words: hypereutectic Al-Si alloy; complex modification; microstructure; mechanical properties  ... using minor element addition is the most popular method due to its simplicity and effectiveness. Phosphor is the most effective refinement element of primary silicon in hypereutectic Al-Si alloy[13-14......

: TG146.2 收稿日期:1999-01-15 Dissolution kinetics of primary silicon for hypereutectic Al-Si alloy Abstract: As well known, coarse primary silicon phase in Al Si hypereutectic alloy dents its mechanical properties, thus limits the application of this alloy. In addition, it has been found that primary silicon in Al Si hypereutectic alloys was of higher chemical......
