材料信息學(xué)及其在材料研究中的應(yīng)用
[Abstract]:The material Genome Project (MGI),) proposed by President Barack Obama in 2011 aims to develop and manufacture advanced materials at a rate of at least twice as fast as before and at a cost of only a fraction of the original cost, which has contributed to the rapid development of material informatics. Material informatics is the application of informatics technology in material science. Material big data is analyzed and predicted by building material information database, integrating material research and design platform and material data mining method. Rapid discovery of the "gene" that determines the properties of materials, that is, the quantitative relationship between material components, processes, and properties, can effectively speed up material development and design. This paper introduces the basic concepts and research fields of material informatics, and describes three main components of material informatics: material information database, integrated material design platform and material data mining technology. The material information database stores and manages all kinds of material data, including material basic performance, crystal structure data, simulation calculation data, test and process data, patent data and various publications. The integrated material design platform provides a variety of simulation methods, such as first-principles, molecular dynamics, CALPHAD method, phase field simulation and finite element analysis; Data mining is an interdisciplinary field of statistics, machine learning, informatics, visualization technology and so on. It is a practical method to discover knowledge from big data. It also introduces the frame and function of the integrated material design platform of "Caizhi Cloud" built by Chengdu Timber Science and Technology. The problems faced by the application of material informatics in the field of materials are considered.
