近年来,材料科学的发展是惊人的,用把各自性能良好的材料组合起来的方法获得在单一材料中所不能获得的性能而创制的复合材料正在飞跃发展。近期的文献指出:“复合材料将引起材料革命”,“二十一世纪将是复合材料的黄金时代”;正期待着划时代的新材料的出现。在金属学领域中、利用状态图的共晶点,用单向凝固法制成的金
In recent years, the development of materials science has been phenomenal. Composites created by combining methods that combine well-behaved materials to gain unattainable performance in a single material are evolving. Recent literature points out that “composite materials will lead to material revolution” and “the 21st century will be the golden age of composite materials.” We are looking forward to the epoch-making emergence of new materials. In the field of metallurgy, using the eutectic point of the state diagram, gold is made by one-way solidification
