Advanced light alloys (aluminum, magnesium and titanium alloys) are increasingly being used in the automotive, aerospace and consumer industries for weight reduction and structural efficiency. This talk will provide examples of designing and developing new lightweight metallic materials, including 1) Al and Mg alloys for high-pressure die casting; 2) Mg alloys for extrusion and sheet applications; 3) Ti alloy for permanent mold casting; and 4) high-entropy alloys for solidification and powder-based processing. The talk will also summarize some of the latest process innovations in developing/optimizing casting, extrusion, sheet forming and multi-material manufacturing processes. A Super vacuum die casting (SVDC) process is developed to produce integrity and thin-wall Al and Mg die castings. A new setup including an induction to skull melting (ISM) system, a gravity tilt-pour system, and a ceramic-coated steel mold has been developed to produce near-net-shape titanium castings, using a low-cost permanent mold casting process. Improved extrusion, sheet and tube forming processes have been developed for Al and Mg alloys. 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 alloy development and advanced processing of light alloys using ICME tools. Advanced solidification and precipitation models for light alloys have been developed using computational thermodynamics and kinetics, combined with microstructure and process modeling techniques. These solidification and precipitation models are being integrated to predict location-specific mechanical properties, based on location-specific microstructure, of light alloy castings for structural applications.
