Abstract

In this study, a novel Al-Si-P master alloy has been successfully prepared to modify and refine primary Si in eutectic and hypereutectic Al-Si alloys. Since Si has similar crystal structures and lattice parameters with AlP, it can control the distribution of AlP in Al-Si-P master alloy. With addition of Al-Si-P master alloy, AlP particles pre-formed in Al-Si-P master alloy can nucleate primary Si which contribute to the precipitation and refinement of primary Si in eutectic and hypereutectic Al-Si alloys respectively. Forthermore, Al-Si-P master alloy has the advantages of stable and long-term modification efficiency, simple operation, no pollution to environment and low comprehensive cost, and can be used widely in the aluminum industry.

摘要

研制了一种高效且适用性强的Al-Si合金变质剂——Al-Si-P中间合金。由于AlP与Si具有相似的晶体结构

中间合金中Si的引入起到了促进AlP均匀分布的作用。该中间合金含有大量AlP颗粒

加入到共晶和过共晶Al-Si合金中后

分别起到促进初晶硅析出和细化初晶硅的作用。该中间合金具有变质效果好、长效、无污染、使用简便和使用成本低等优点

具有广阔的应用前景。
