Greetings from the Program Director
‘Materials Integration for Revolutionary Design System of Structural Materials’, one of the subjects of the Cross-ministerial Strategic Innovation Promotion Program (SIP)*, was started in FY2018 and is now half way through its five year duration. To strengthen the global competitiveness of Japan’s materials and related industries, world-first materials integration (MI) system are being developed which combine materials engineering methods, experiments, theoretical computations, and data science to connect processing, structure, property, and performance on computers to accelerate R&D. ‘MInt’ for structural metallic materials and ‘CoSMIC’ for CFRP are our two main MI system, and systems for intermetallic compounds and ceramic matrix composites are also being developed. These systems contain inverse design functionality, which can form the conditions of materials and manufacturing processes necessary to realize a material’s desired performance.
Regarding practical results application, our goal is to have our MI system be broadly utilized by industry, academia and government to support their materials R&D. For this purpose, organizations have been established which also enable non-SIP member institutions to use them. We strongly hope that the products and technologies developed using our MI system will be commercialized for real-world application. We appreciate your continued support for our endeavors.
＊SIP is a national program led by the Council for Science, Technology and Innovation（ CSTI） of the Government of Japan, using interdisciplinary management to realize scientific and technological innovation.

Materials Integration System
The major purpose of our MI system is to reduce costs and shorten development periods utilizing material engineering methods and data science that combine computational science, theory and experimentation, primarily by virtually reproducing materials events on a computer.
The MI system deals with cutting-edge structural materials and manufacturing processes. The main reasons for choosing structural materials are that their life time can be several decades long and accordingly their highly-precise R&D is timeconsuming and expensive. We aim to get benefits in shortening development periods and reducing costs from using the MI system.
Our R&D system is composed of three domains with 12 teams (44 organizations in total). Domain A (A1 to A5) - establishment of the Inverse Design MI Basis; Domain B (B1 to B3) - applications to CFRP: Domain C (C1,C2,C4,C5) - application to 3D
Domains B and C feed back physical data to Domain A and use the knowledge acquired by Domain A for actual materials and processing development, in order to verify its effectiveness.
Overview of MInt (Materials Integration by network technology)
Based at the National Institute for Materials Science (NIMS), we are developing ‘MInt’ for structural metallic materials in cyberspace. By creating a workflow that connects computational tools called modules, we can predict processing, structure, property and performance in quick succession. As an example, an experiment that normally takes half a month can be shortened to half a day in cyberspace. Furthermore, we can combine MInt with other kinds of optimization methods in order to propose the optimal processing and structure considering the desired performance.
MInt has distributed computation functionality, through which a workflow can be computed in confidentiality. Each company can locally run a part of workflow in its own computing environment ensuring security when using its confidential data, and only the computed results are fed back outside to complete the computation of the workflow. We aim to make a user friendly system, available from distant locations via the Internet and supported with multimedia tutorials (MIntMedia).
Overview of Materials Integration Consortium (MI Consortium)
In order to make MInt useful for society, NIMS manages the ‘Materials Integration Consortium (MI Consortium)’ established through industry-academia-government collaboration. The MI Consortium promotes material innovation through collaborative research based on MInt. And it is continually improving MInt by implementing modules and workflows developed through collaborative research, enhancing the R&D capacity of industry and academia members that use MInt.
Overview of CoSMIC (Comprehensive System for Materials Integration of CFRP)
‘CoSMIC’ is being developed at Tohoku University as an MI system for carbon fiber reinforced plastics (CFRP). 12 modules aimed at CFRP design for aircraft structures have been developed so far, and multi-physics/multiscale simulations from atom to structure scale can be performed. In the future, in response to growing user needs, developing modules to support product development outside the aircraft industry is also planned.
Users can access the system remotely and use the supercomputer at Tohoku University to perform large-scale and high-speed calculations. The system can be operated via a GUI and together with the easy-to-understand manual offers a userfriendly experience
Overview of the utilization promotion committee for CoSMIC
As with MInt, a consortium for CoSMIC is planned to establish at Tohoku University to be used this system by many companies. In 2020 a committee to promote utilization of CoSMIC was set up as a preliminary step to establish a consortium. Here, how to use CoSMIC is lectured for companies planning to join the consortium, including nonparticipants of SIP, and consortium operational policies and bylaws are being discussed.

Establishment of the Inverse Design MI Basis for Advanced Structural Materials and Processing
The establishment of an integrated materials development system aiming to realize Society 5.0, which proposes required structure and properties of materials to fulfill desired performance and also enables presentation of its potential processing. We will also further develop advanced structural materials and processing, in which Japan has strength and the importance of which will increase in future.
Applications of the Inverse Design MI to Actual Structural Materials（CFRP）
The development of technologies related to the improvement of property and productivity of CFRP, which are becoming widely used as materials for lightweight structure, by integrated materials development system. This will enable us to lead the world in the development of transport equipment such as aircraft.
Applications of the Inverse Design MI to Actual Structural Materials（3D Powder Processing）
The realization of innovative materials and processes utilizing integrated materials development for 3D powder process of heat-resistant alloys with intense development competition and CMCs which are super high temperature heat-resistant materials for next-generation transportation and energy equipment, and this development will strengthen industrial competitiveness in Japan.
Research and Development Overview（Domains / Teams)
Our R&D system consists of three domains with 12 teams – the Domain A （5 teams）: the establishment of the Inverse Design MI Basis for Advanced Structural Materials and Processes （Inverse Design MI）, the Domain B (3 teams） : the applications of the Inverse Design MI to Actual Structural Materials（CFRP）and the Domain C （4 teams）: the application of the Inverse Design MI to Actual Structural Materials(3D Powder Processing）. the Domain A carries out basic technology development of MI systems such as calculation modules, databases, workflows, inverse problem solution methods, and development into advanced materials and processing. The Domains B and C, as potential users, use the technology developed by the Domain A for the actual materials and processing development in order to demonstrate its effectiveness.
