CMI scientists at Lawrence Livermore National Laboratory led this research.
Achievement:
An Al-3.5Ce-0.4Mg-7Si alloy with improved casting and mechanical properties was developed with CALPHAD
Significance and Impact:
- Collaboration with Eck Industries and ORNL resulted in a new alloy composition
- Freezing ranges were computationally optimized to alloy for Additive Manufacturing (AM) conditions
- An ROI and publication is underway
Details and Next Steps:
- Established a feedback loop between the partnership
- Determined composition ranges by empirical relationships
- Performed casting experiments
- Thermodynamic calculations aided in optimizing freezing ranges for Ce modified A-356 alloys
- Additional Ce-modified Al alloy compositions are to be defined and included in a non-provisional patent filing
