为满足提高燃油效率及汽车“轻量化”等方面持续的需求,学术界及工业领域一直都很重视钢铁及其替代材料的研发,这两类材料之间的竞争始终十分激烈。对汽车用钢在北美的研究现状进行了概述,并重点介绍了几种冷轧和热轧汽车用钢的研究进展及其生产情况。新一代先进高强钢的发展将依然令人关注并充满机遇。
In order to meet the continuous demand for improving fuel efficiency and automotive “lightweighting”, the competition between the two types of materials has always been fierce. The academic and industrial fields have always attached great importance to the research and development of steel and its substitute materials. The research status of automobile steel in North America is summarized, and the research progress and production of several kinds of steels for cold rolled and hot rolled automotive are emphatically introduced. The development of a new generation of advanced high strength steels will continue to be a source of concern and opportunity.
