Structure of liquid aluminium-silicon alloys
- 169 Downloads
The Kumar-Samarin technique of centrifuging was adopted to study the structure of aluminium-silicon alloys in terms of the concept of the existence of clusters in liquid state. The investigation shows that in hypo-eutectic alloys the clusters are denser than the monatomic matrix whilst in hyper-eutectic alloys they are lighter. It is suggested that this difference in the distribution of silicon in liquid state could account for the difference in the solidification behaviour of hypo- and hyper-eutectic alloys.
