| Abstract: | The in-situ fibrous Si phase microstructure was obtained in as-cast Al-Si hypoeutectic alloy under the combined effects of rapid solidification and modification.The evolution of Si-phase morphology under such effects was discussed.Focus was based on the modification mechanism of the alloy.Furthermore,the effect of cooling rate on the morphology evolution of Si was discussed.This paper introduced a new approach of fabricating the straight fiber-reinforced Al-based composite. |
| Keywords: | Al-Si hypoeutectic alloys Si morphology rapid solidification modification |
