DX時代の材料開発をリードするQuesTekの材料設計アプローチの紹介

抄録

Since materials research and development require significant time and cost, there is increasing demand for improvements and optimization in materials design and practical production. QuesTek's materials design approach is based on the concept of Integrated Computational Materials Engineering (ICME), which leverages computational science over multi-scale, integrated simulations. This approach is characterized by using physics-based computational models to predict material properties. For the issue of scale-up for actual manufacturing, Accelerated Insertion of Materials (AIM) method is used, which combines computational models, data-driven methods, and statistical methods to quantify material composition tolerance and heat treatment uncertainty with small amounts of data, and predicts variations in property values and minimum design tolerances at manufacturing scale. QuesTek's proven material design approach enables rapid, accurate, and realistic material modeling, allowing for the property prediction and the process optimization through prototyping and full-scale manufacturing. In this paper, we introduce QuesTek's materials design approach with some case studies.
