Lightweight Materials and Advanced Manufacturing for Sustainable Transportation

Abstract:  

Lightweight materials such as aluminum, magnesium, titanium, and metal matrix composites are increasingly adopted in the transportation sector to minimize energy consumption and reduce carbon emissions. Emerging materials including high entropy alloys and densified superwood materials are also promising in transportation applications. Integrated Computational Materials Engineering (ICME) is defined as the integration of materials information, captured in computational tools, with engineering product performance analysis and manufacturing-process simulation. This talk presents some examples of lightweight material design and development using an ICME approach based on CALPHAD (CALculation of of PHAse Diagrams) and artificial intelligence/machine learning (AI/ML) methods. The presentation will also discuss some of the latest innovations in sustainable casting and multi-material manufacturing processes. The development of large thin-wall die casting (giga-casting), using solidification-based ICME tools, will improve the sustainability of transportation manufacturing. Microstructure models for light alloys have been developed based on computational thermodynamics and kinetics, coupled with manufacturing process models. These ICME models are integrated to predict location-specific mechanical properties, based on location-specific microstructure of solidification (casting, welding and additive manufacturing) products, for lightweight and sustainable applications.
