Our Lab. aims to Elucidate Metallurgical Phenomena during Welding
based on Materials Science & Engineering
and to develop innovative welding & joining technique.

Development of innovative manufacturing technology is required to manufacture high-performance machine products and structures of the next-generation. Department of Reliability Evaluation & Simulation conducts research and education for elucidation and control of the factors on weldment properties by high accurate evaluation based on material science and engineering. In order to create innovative and attractive technique of welding & Joining as a final aim, our department are working on elucidation of metallurgical phenomenon such as solidification and transformation, and on developing the predication method for the microstructures and the properties of weldments.

  • Elucidation of mehcanism of microsturucural evolution (solidification, phase transformation etc.) during welding & joining
  • Elucidation of infuluencing factors on defect formation (hot, reheat & cold cracking) and the mechanical properties of weldments
  • Development of technique for property modification and reliability evaluation by innovative method of microstructure control
