| Abstract Scope |
Automotive manufacturers are increasingly using aluminum alloys to reduce the weight of vehicles and as a result improve their fuel efficiency/performance. Advanced aluminum alloys with targeted properties needs to be developed faster, especially with the introduction of electric vehicles. In the current work, we have developed a physics informed machine learning framework to explore 6xxx aluminum alloy chemistry space for targeted product performance criteria. Computational thermodynamics methods were used to estimate microstructure features on historical alloy design data. These features were integrated with machine learning (ML) methods to estimate strength, ductility, formability and corrosion performance of 6XXX aluminum alloys. We used multi-objective genetic algorithm optimization to identify alloy chemistries that met or exceed the performance targets for specific automotive applications. We conducted a lab trial for selected alloys and their properties were evaluated and compared with the ML model predictions. The framework developed enables accelerated design of aluminum alloys. |
