The objective of this project is to study a new method to control crystal orientation of an iron sheet by using press machine. Firstly, an equipment to conduct experiments which adds vibration of shear stress to an iron sheet specimen was developed. After shear stress was added to a specimen many times by the equipment, the specimen was annealed. Then the distributions of crystal orientation were analyzed by an EBSD. It was found from the experiments that grains of particular crystal orientation was grown to be very large grains. Possibility of crystal orientation control was shown.
