Liquid structure of Al-Si alloy: A molecular dynamics simulation
Source abstract
Abstract
Abstract Liquid structure of Al-Si alloy is a long-standing issue. Using the newly-developed Al-Si potential, we studied the liquid structure of Al-10.3 wt% Si alloy by molecular dynamics simulation for the first time. We found that Al and Si atoms tend to be well mixed and the aggregation of Si-rich clusters is weak. The results exclude the possibility of regarding the aggregation of Si-rich clusters as the origin of the hysteresis in liquid Al-Si alloy. We didn't find obvious abrupt structure change in liquid Al-10.3 wt% Si near the melting point of Al.
