Vehicle efficiency (in terms of fuel consumption) and reduction of carbon dioxide emissions continues to be a major challenge for the automotive industry. Light metals such as aluminum and magnesium alloys are of considerable interest to automobile manufacturers because of their low densities. The major drawback of using light metals is their relatively low formability compared to carbon steels. While their limited formability prevents them from being used in certain structural parts, advanced alloying and manufacturing processes enable them to be used in outer body applications. The proposed research will combine the latest advancements in the fields of micromechanics, finite element methods, multi-scale modelling and super computing, for the ultimate goal of enhanced ductility in aluminum and magnesium alloys to increase the amount of light metals employed in a vehicle. This research will serve as a guide for both material scientists and engineers in the automotive industry since the outcome of the research will clearly demonstrate the microstructural and mechanical properties necessary in aluminum and magnesium alloys to achieve improved formability.
