摘 要：The novel Al-5Ti-1B-1RE nanoribbons were synthesized by melt-spinning.The microstructure showed that the Al-5Ti-1B-1RE nanoribbon consisted of granular-like TiB2 and core-shell-like TiAl3/Ti2Al20Ce.The Al-5Ti-1B-1RE nanoribbon could give rise to the excellent refining effect on as-cast A356 alloys.The refining efficiency and formation mechanism of Al-5Ti-1B-1RE nanoribbons were investigated.In accordance with the experimental results,it could be seen that the Al-5Ti-1B-1RE nanoribbon could maintain the refining effect after 60 min of holding.Additionally,owing to the addition of Al-5Ti-1B-1RE nanoribbon,the mechanical properties of A356 alloys could be enhanced significantly.
