日本将建立由产业界、学术界和政府部门组成的所谓产学官合作攻关小组,在从明年起的5年时间内投资100亿日元,重点开发金属玻璃批量生产的途径。 金属玻璃是由铁、铝、钛、铜这4种元素组成的具有非晶态即玻璃结构的合金,所以又称玻璃合金。它的强度是钢材的两倍,耐腐蚀性能可以达到钢材的3倍以上。金属玻璃具有很多优点,应用潜力很大,但目前的制造工艺成本高昂,难以批量生产。所以,金属玻璃现在仅用作高尔夫球杆等部分体育用品的材料,尚未能在工业生产中普遍使用。 日本经济产业省的官员说,如果能实现批量生产,那么金属玻璃将可以在制造微型机械、燃料电池隔板、光通信接线柱、人造牙根、飞机零部件、汽车阀门簧等方面得到广泛的应用。为此,由经济产业省牵头,日本国立
Japan will establish a so-called cooperation among industry, academia and government departments to launch an inter-disciplinary research team to invest 10 billion yen in five years starting next year, focusing on the development of mass production of metallic glass. Metallic glass is composed of four elements of iron, aluminum, titanium and copper, which have an amorphous or glassy structure, so it is also called glass alloy. Its strength is twice the strength of steel, corrosion resistance can reach more than 3 times the steel. Metallic glass has many advantages and potential applications, but the current manufacturing process is expensive and difficult to mass produce. Therefore, the metal glass is now used only as a material for some sporting goods such as a golf club, and has not been widely used in industrial production. Officials at Japan’s Ministry of Economy, Trade and Industry said that if mass-production is possible, metallic glass will find widespread application in the manufacture of micromechanics, fuel cell separators, optical communications terminals, artificial tooth roots, aircraft components, automotive valve springs and the like . To this end, led by the Ministry of Economy, Trade and Industry, Japan’s national government
