在轻金属中,镁是最轻的结构金属,虽然这种材料只有小部分用作结构材料使用,但是预计在90年代该材料用于结构件的消耗量将呈指数上升。其原因是,该材料除密度小之外,还易于生产和加工以及能改善合金状态。文中介绍了超轻镁合金的未来发展,镁复合材料和快速凝固以及新的生产方法,这一切都有助于镁材得到广泛的工业应用。 In light metals, magnesium is the lightest structural metal and although only a small part of this material is used as a structural material, it is expected that the consumption of the material for structural members will increase exponentially during the 1990s. The reason for this is that besides being small in density, the material is also easy to produce and process and to improve the alloy’s state. The article describes the future development of ultra-light magnesium alloys, magnesium composites and rapid solidification and new production methods, all of which contribute to the magnesium industry has been widely used in industry.
