In this study, we try to reveal the relationship between the plastic deformation and the microscopic crystallographic misorientation evolution by using our multi-scale finite element (FE) code by using a crystallographic misorientation theory. We employed two-scale structure, such as a microscopic polycrystal structure and a macroscopic elastic plastic continuum. Our analysis code predicts the deformation...
We have developed power electronics course in electrical engineering class for university students in teacher training faculty who have not background of physics and advanced mathematics at high school. The purpose of this course is to let students understand that power electronics is one of vital and realistic solutions for environmental and energy problem. An educational induction heating machine...
Anisotropic Nd-Fe-B-Cu powder was fabricated by grinding melt-spun and subsequently hot-rolled materials. We prepared two types of powder with different particle shapes: one isotropic shape, and the other a flat shape with the c-axis perpendicular to the flat face. Perpendicular-field pressing experiments show that isotropic particles are better aligned in the bonded magnet than are flat particles...
