metastable materials MeansthermodynamicsA large class of materials in metastable state can be used as both structural materials and functional materials, involvingMetallic materials、Inorganic non-metallic materialsandPolymer materials。Metastable materials can be metastable in composition, structure and morphology.On the one hand, because metastable materials have special properties that many conventional stable materials do not have, they have broad application prospects in many fields of the national economy;On the other hand, because metastable materials are obtained under abnormal conditionsmetastable materials The field has also become an important source for human beings to discover new substances and new physical phenomena, and is also an internationalmaterial science One of the important hot research fields in the research field.However, China's research in the field of metastable materials is scattered in different disciplines and research units. The research direction is too narrow, too specialized, and the research conditions are poor, which seriously restricts the improvement of China's research level of metastable materials. Therefore, it is very necessary to establish a national key laboratory for the preparation technology and science of metastable materials.The purpose of building this laboratory is tometastable materials Major basic scientific issues and key technologies in the research fieldmetastable materials Scientific research base, talent training base and academic exchange base.The laboratory takes metastable material preparation technology and science as the theme, based on basic and applied basic research, and focuses on application development.For this reason, the laboratory conducts research work closely around three academic levels - basic theory, preparation technology and application basis.In terms of basic theoretical researchmetastable materials Carry out in-depth and systematic research on common basic scientific issues in the field, and further strengthen the research team in basic theory through talent introduction to form characteristics.In terms of preparation technology and applied basic research, we will aim to undertake major national scientific research tasks, develop new materials and new technologies, and extend them to engineering applications, focusing on new materials and new technologies in national defense, energy, transportation and automobile industries.
