Computational Metallurgy Lab. is developing next-generation high-performance steel materials, which are key materials for future mobility, energy production, transportation and storage, and building safe social infrastructure. We present a new technological paradigm that can dramatically overcome the physical property limits of currently used steel materials through analysis of microstructure formation mechanism based on thermodynamic/phase transformation theory and advanced analysis techniques and innovative microstructure control technology based on alloy/process design. We are working hard to do research.
