Recently, the major of Beijing science and technology plan projects - "research and industrialization of amorphous and nanocrystalline products" passed the municipal science and technology commission experts acceptance of the organization. This is the Beijing municipal science and technology commission to organize and implement the "capital of the 248 major innovation project" in the major of science and technology plan projects since the first batch of one of the major achievements obtained. At the same time, the successful implementation of this project also marks in amorphous and nanocrystalline materials in China, the ability of process equipment and industrialization of whole to achieve the leap development of the world's top three.

"Research and industrialization of amorphous and nanocrystalline products" project, started in 2002, is a key support spent 12 million yuan science and technology commission of one of the major science and technology plan projects in Beijing. The project by the antai technology co., LTD., Beijing university of science and technology and institute of Chinese academy of sciences, altogether is composed of four subsystems subject: "industrialization of nanocrystalline alloy thin belt", "amorphous material, nanometer whiskers and its applied research", "bulk amorphous materials technology research", "amorphous and nanocrystalline generic technology platform and information". Through the implementation of the project, the project team a total of 18 applied for national invention patents, to formulate and promulgate the three national standards, and realize the breakthrough in four aspects: one is developed with high saturation magnetic induction intensity and magnetic permeability of amorphous and nanocrystalline materials, broke through the thin belt (22 microns) stable and continuous production key technology, built with annual capacity of 500 t production line, make our country broke the foreign relevant patent restriction, in home appliances and communication power supply with high quality nanocrystalline core industries have independent intellectual property rights; 2 it is developed for force, magnetic sensor with high sensitivity, break through the spinning round water in the continuous preparation of whiskers and glass cladding material series of key technologies, established the international advanced level of production line, the demonstration products can be applied to vehicle speed sensor and anti-theft security, etc; Three is the independent development of copper - zirconium binary amorphous alloys and iron-based amorphous alloys and its superplasticity forging and extrusion molding process and equipment, greatly reduce the cost of materials, enlarging the application scope of the bulk amorphous materials; The four is built of amorphous and nanocrystalline alloy materials applied research and product development of generic technology platform, which laid a foundation for sustainable development in this field.

Application of amorphous and nanocrystalline materials is our country started from "the purpose of" continuing to pour money into power to conduct researches in key areas, after four five years before the implementation of the scientific research plan, the amorphous alloy strip has been basically achieved and products of industrialization, but the product has been in a mid-range applications. In recent years, the rapid development of electronic information technology, on the basis of small, high efficiency, energy saving the rapid increase of the demand of electronic components to amorphous and nanocrystalline materials, put forward the urgent request. In this respect, our country because of backward technology and equipment, material quality is not high, the application is limited by a lot, high-end products mainly rely on import of our country's market. The "research and industrialization of amorphous and nanocrystalline products" major science and technology plan projects in the development of amorphous and nanocrystalline materials, has made a major breakthrough, break through the key technology for our country in amorphous and nanocrystalline material system, ability of process equipment and industrialization of whole realized leap-forward development, greatly improve the position of our country in this field.
