据报道,在美国汽车减重计划中,要把1978年平均每升汽油行走7.7公里提高到1985年行走11.7公里的基准,汽车要减重30％。而每辆汽车使用含铌低合金钢200公斤可以做到这一点。北大西洋条约组织设计的坦克和战斗机,也准备采用含铌超耐热合金。目前,人们对金属铌的研究和使用越来越感兴趣,估计未来铌的消费量将大幅度增大。

It is reported that in the U.S. car weight loss program, it is necessary to raise the average of 7.7 kilometers per liter of gasoline in 1978 to the standard of 11.7 kilometers in 1985, and the car should be 30% less heavy. This can be done with 200 kilos of niobium-containing low-alloy steel per car. The North Atlantic Treaty Organization designed tanks and fighters, also prepared to use niobium-containing superalloys. At present, people are more and more interested in the research and use of metallic niobium, and it is estimated that the consumption of niobium will increase significantly in the future.
