Background of Experiment
□ Al-Si Alloy
AI + Si = Al-Si Alloy
1. Low melting point
2. light
3. Large heat capacity
4. Insoluble to each other

Result and Analysis - EDS
□ Composition Analysis
Al, Si is almost insoluble to each other at rsoom temperature.
All solid phase will have either 100% Al phase or 100% Si phase.
