Innovating the model of materials R&D, accelerating the process of materials R&D, and reducing the cost of materials R&D are the common concern of all countries in the world. Integrated computational materials engineering (ICME) and materials genome initiative (MGI) are novel ideas and methods in the field of materials science and engineering in recent years, both of which bring new insights and opportunities for research and development of new materials. ICME is a fundamental component of MGI. Materials genome initiative includes three major elements: highthroughput experiments, highthroughput calculations, and material databases. Materials genome initiative extends the concept of ICME to the entire material science, technology, and engineering chain, and extends throughout the entire process from discovery of new materials to application. As a new concept and new model for the research and development of new materials, ICME and MGI will certainly play an irreplaceable role in the development of new materials. This article briefly reviews the development history and major problems of materials research, and details the intrinsic connections and differences between MGI and ICME. Through four application examples (gradient cemented carbide, CVD hardcoating, lithiumion battery, aluminum alloy), the powerful functions of ICME and MGI in material R&D are demonstrated, which provide new methods for materials design and development. Meanwhile, the key points and trends in the future development of ICME and materials genome initiative are also anticipated.
