| Research Abstract |
In order to refine microstructure of displacive transformation, intragranular nucleation, which has been used in the diffusional transformation, has been applied. It was found that, unlike to diffusional transformation, effects of inclusion or precipitates within matrix grains are small while deformation prior to transformation accelerates intragranulear nucleation of martensite or baintie, leading to refinement of microstructure.
Furthermore, novel characterization method has been developed on a basis of precise measurement of orientation relationship between product and matrix phases and reconstruction method of austenite matrix.
