Summary
We have developed a novel numerical technique to simulate microstructure evolutions in metallic materials during solidification, phase transformation and recrystallization by using phase-field method. The phase-field method has attracted much attention as a powerful simulation tool for simulating the microstructure evolutions. Recently, the method has been applied to simulate electrochemical phenomenon in lithium ion battery and fuel battery. Furthermore, we develop a new simulation method coupled the phase-field method with finite element method to apply it to various field, such as mechanical engineering, materials science, electric engineering and chemical engineering. We have also develop parallel computing technique using GPU to accelerate three-dimensional simulation which is necessary to develop practical materials and devices.
