Development of new materials based on the concept "Phase Stability Control"

photo

There are many states including equilibrium and metastable states which are fromed from non-equilibrium (high-energy states, excited states).
Various materials can be obtained by the microstructure control based on "Phase Stability Control".
The important targets are summarized by the following two points;
(1) How to achieve the non-equilibrium state?
(2) How to control to change from non-equilibrium to equilibrium/metastable states?
To achieve the development of new materials based on "Phase Stability Control", the followings three techniques are investigated;
(1) Alloy design: Thermodynamic calculation, ab-initio calculation, Data base science.
(2) Microstructure analysis: Electron microscopy, In-situ observation, trans-scale observation
(3) Microstructure control: Solidification and casting, Electron Irradiation

(1) High Entropy Alloys
