Abstract:
Cooling curve analysis (CCA) was conducted in a graphite crucible using K-type thermocouples. Solidification temperatures of the basic phases were identified based on past literature techniques; and curves were plotted in conjunction to collected Microsoft Office-Excel raw data. Start of solidification, dendrite coherency temperature (DCT), Al-Si, Al-Si-Cu, and end of solidification temperatures were identified. Optimal solution heat treatment temperature of these alloys was recommended to be 500'C.
