  19. published software

  20. New book being written by R. Qin on phase-field modelling, based on his teaching in GIFT

  21. Interactions with Industry POSCO: Transfer of software for strength of hot-rolled steels POSCO: Transfer of software for TTT diagram calculation POSCO: Transfer of software for TRIP-steel simulations ESAB (Sweden): Transfer of software for strength of welds

  22. Interactions with Industry • Student collaboration on TRIP steel (Guo Lei, WeiJei Liu) • BOT: -TRIP (Swarup Ghosh, Hong Liang Yi) • BOT: Electropulsing (Rongshan Qin) • Precursor to BOT: Simultaneous casting (Yong Ki Kim, Rongshan Qin) • BOT: Superbainite • BOT: TWIP-assisted steel (WeiJei Liu) • Hot-press forming (Shgh Woei Ooi)

  23. Interactions with Industry In Gee Kim, KISTI Supercomputer Expert for (Small and Medium Business) Support

  24. Strategy science publication in journals effective dissemination effective local, national and international collaboration lead industry with new steel concepts good teaching

  25. Role of models is often overstated. Scientific progress can happen from simple observations. perfect computation simply reproduces Nature, does not explain her Anderson, Nobel Laureate, 1977

  26. lead to unexpected outcome, verifiable • created or used in hindsight to explain diverse observations • existing models adapted or grouped in novel manner to design • used to express data, reveal patterns or implemented in control algorithms

  27. Charpy fatigue tensile critical stress intensity corrosion
