冶金学家早已知道,某些处于熔态的金属迅速冷却时就会变成为非常有用的新材料。过去对于这种新材料的开发还限于实验室,然而今天工业界已把注意力转向这种新材料了。 当一种金属以每秒一百万摄氏度的速度冷却时,它的结构就会变成为非晶态结构,而不 Metallurgists have long known that certain metals in their molten state become very useful new materials when rapidly cooled. In the past the development of this new material was still limited to the laboratory, but today the industry has turned its attention to this new material. When a metal cools at a rate of one million degrees Celsius per second, its structure becomes amorphous and not
