本文作者1979年应冶金部邀请访华。本文是他在北京所作学术报告纪录稿(本刊有删节)。文中介绍了美国汽车工业进入80年代后面临的挑战:燃油经济性,排气污染与安全等。说明为了满足政府对上述三项的规定,必需减轻汽车的自重,对制造汽车用的材料,将需要重新估计。进入80年代后,低合金高强度钢、铝及铝合金和塑料的使用将增加,给出增加的具体数字和制造的另件种类,指出使用高强度钢时需要注意其冲压成形性,并给出实例,最后介绍新型材料碳纤维组合材料的性能和使用。
In 1979, the author of this article invited China Metallurgical Department to visit China. This article is a record of his academic report in Beijing (abridged version of this issue). The article describes the challenges that the U.S. auto industry has faced since the 1980s: fuel economy, exhaust pollution and safety. Explain that in order to meet the government’s stipulations on the above three items, it is necessary to reduce the self-respect of automobiles and the materials for the manufacture of automobiles will need to be re-estimated. After the 1980s, the use of low-alloy high-strength steel, aluminum, aluminum alloy and plastic will be increased. Given the specific numbers added and the kinds of other articles manufactured, it is pointed out that the use of high-strength steels requires attention to their press formability, An example, and finally introduces the performance and use of new material carbon fiber composite materials.
