| Research Abstract |
This project focused on development of novel solidification processing using magnetic field effects for controlling microstructure. Time-resolved X-ray imaging developed by this project has allowed us to observe solidification in various metallic alloys. The observation showed that the regular structure was evolved during unidirectional solidification of Al-In alloys. We also found that the static magnetic field agitated convection in the mushy region for Al alloys. 3-dimensional crystallographic alignment of orthorhombic FeSi_2 particles was achieved by using anisotropic magnetic field. Alignment of TiO_2 particles with diameter of several 100nm was improved.
