Research Abstract |
Microstructural evolution occurring suddenly in nickel based superalloys and heat resistant steels, both of which have the hierarchic structure, was investigated by the phase-field method based on system free energies of them. In this investigation, experimental measurements such as dislocation density were also employed for estimation of the system free energies in ferritic heat resistant steels having a complicated hierarchic structure. Furthermore, the lath martensite structure similar to the real one can be constructed by the phase field simulation.
