Lightweight Car Body and Application of High

Improvement of safety, reduction of energy consumption, and reduction of emission become one of the most highlighted issues for automotive industry in recent years. One of the most significant solutions, i.e. lightweight car body has been described in this paper. Design, implementation, and characterization of parameters of lightweight car body are reviewed as well. In the later part of this paper, the development of high strength steels (HSS) and advanced high strength steels (AHSS) and their typical properties and microstructures are introduced. The application of these high strength steels for lightweight car body can largely improve safety and performance of vehicles.
