摘要

减轻汽车的重量是提高燃油经济性的一个主要因素。汽车制造的基础材料，低碳钢和铸铁，正在被具有更高比强度和刚度的材料所取代，如先进的高强钢、铝、镁和聚合物复合材料。关键的挑战是用这些新材料降低制造结构的成本。最大限度地减轻重量需要优化设计，利用各种形式的多种材料。这种混合材料的使用在连接和防止电偶腐蚀方面提出了额外的挑战。

Materials for Automotive Lightweighting

Reducing the weight of automobiles is a major contributor to increased fuel economy. The baseline materials for vehicle construction, low-carbon steel and cast iron, are being replaced by materials with higher specific strength and stiffness: advanced high-strength steels, aluminum, magnesium, and polymer composites. The key challenge is to reduce the cost of manufacturing structures with these new materials. Maximizing the weight reduction requires optimized designs utilizing multimaterials in various forms. This use of mixed materials presents additional challenges in joining and preventing galvanic corrosion.
