Tohoku University research group headed by
Prof. Kiyohito Ishida,
Graduate School of Engineering, has succeeded in
developing cobalt(Co)-based high temperature alloys having an even higher
strength at high temperatures than the conventional Ni-base super alloys.
The research group has conducted studies
to calculate on the alloy phase diagram, which shows structure and stability of
phase in alloys using computing simulations. |
