近一、二十年来,材料科学的研究与发展有了许多新的突破,这不仅表现在象复合材料、精密陶瓷等新材料的出现,也表现在作为传统材料的钢铁、合金的生产中采用了许多新技术、新工艺,从而使它们产生了新的活力。从熔融金属高速冷却凝固的急冷(Rapidly Cooling)技术或高速淬火(Rapidly Quenched)技术就是其中的一种,应用这种新技术可以在传统合金的基础上产生出一种重要的新材料——微晶合金。 In the past one or two decades, there have been many new breakthroughs in the research and development of materials science, not only in the emergence of new materials such as composites and precision ceramics, but also in the production of steel and alloy as traditional materials Many new technologies, new processes, so that they have created a new vitality. One such technology, Rapidly Cooling or Rapidly Quenched, that cools and solidifies from molten metal at a high rate, can produce an important new material based on conventional alloys - Crystal alloy.
