有色金属材料 发展的主要特点 1.有色金属材料发展的高技术化 高性能有色金属新材料是知识密集型和技术密集型产品,其发展与新技术密切相关。从新型材料的合成与制造来看,往往是利用极端条件或技术作为必要手段,如超高压、超高温、极低温、超高速冷凝及超高纯等。 一项新技术或新工艺的采用往往可以大幅度提高材料的性能。如快速冷凝技术能使液态金属变成非晶态材料,从而获得晶态合金材料所不具备的特性;金属间化合物、硼纤维和碳纤维强化技术的
The main features of the development of non-ferrous materials 1. Non-ferrous materials development of high-tech high-performance non-ferrous metals new materials are knowledge-intensive and technology-intensive products, its development and new technologies are closely related. From the new material synthesis and manufacturing point of view, is often the use of extreme conditions or technology as a necessary tool, such as ultra-high pressure, ultra-high temperature, cryogenic temperature, ultra-high speed condensate and ultra-pure. The adoption of a new technology or new process can often dramatically improve material performance. Such as rapid condensation technology can make liquid metal into amorphous material, so as to obtain the crystalline alloy material does not have the characteristics of intermetallic compounds, boron fiber and carbon fiber reinforced technology
