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.

车辆效率（在燃料消耗方面）和减少二氧化碳排放仍然是汽车工业面临的主要挑战。轻金属如铝和镁合金因其低密度而引起汽车制造商的极大兴趣。使用轻金属的主要缺点是与碳钢相比，它们的成形性相对较低。虽然它们有限的成形性使它们无法用于某些结构部件，但先进的合金化和制造工艺使它们能够用于车身外部应用。该研究将结合微观力学、有限元方法、多尺度建模和超级计算等领域的最新进展，最终目标是提高铝镁合金的延展性，从而增加汽车中轻金属的用量。这项研究将为汽车行业的材料科学家和工程师提供指导，因为研究结果将清楚地展示铝和镁合金的微观结构和机械性能，以实现改进的成形性。
