我国汽车材料发展的几点史实和车辆用材的某些考虑

本文回顾了我国汽车工业发展简史和用料总量。回顾了国际封锁禁运下,我国如何自力更生地开发适合我国资源条件的汽车合金钢系列和低合金高强度钢板系列,节约了镍铬;并论证大量生产的大件商品——汽车必须考虑节约稀缺资源。关于汽车构造基体金属的探讨,突出了现代铸铁的技术进步;对铝、镁、钛用于汽年的前景也作了思考。本文最后讨论非金属材料中的木材、竹材和塑料,提出金属与非金属材料的最佳组合将对今后的汽车作出贡献,孕育出一代代的新型汽车。

Some Historical Facts of Chinese Auto-material Development and Consideration on Vehicle Material Selection

In this paper the history of Chinese auto-industry and total materialconsumption are reviewed. Under international sanction against in earlydays of the People's Republic of China,the chinese industry, on the basisof national self-reliance, developed Series of alloy steel bar grades andHSLA steel sheet grades, achieving considerable economy on nickel andchromium.The paper also presents viewpoint that for this mass-producedlarge piece of commodity--auto-vehicle, the economy of scarce resourcesis rational and quite unavoidable. The discussion on base metals for auto construction pays special att-ention to technical advancement of modern cast iron. Future wider use ofaluminium and magnesium is anticipated. The paper deals finally on non-metals, with discussion on wood, bamboo and plastics. It is put forwardthat the best combination of various metals and non-metals will contri-bute much to the advancement of automobiles.By utilization of new ma-terials, new generations of automobiles will one ofter another come tothe world.
