A Simple Model to Estimate Solidification Time–Dendrite Arm Spacing Relationships in Cast Aluminum Alloys with Two Major Alloying Additions: Application to the Al-Si-Cu System

A Simple Model to Estimate Solidification Time–Dendrite Arm Spacing Relationships in Cast Aluminum Alloys with Two Major Alloying Additions: Application to the Al-Si-Cu System

Secondary dendrite arm coarsening model developed by Feurer and Wunderlin was used in this study. The parameters of the model were adjusted by following a simple approach to find an equivalent eutectic composition based on the alloying additions. Results showed the simple model proposed in this stud...

Zusammenfassung:Secondary dendrite arm coarsening model developed by Feurer and Wunderlin was used in this study. The parameters of the model were adjusted by following a simple approach to find an equivalent eutectic composition based on the alloying additions. Results showed the simple model proposed in this study provided good fits to data from literature on the 319 alloy as well as Al-Si-Cu alloys with various compositions.
