• Magnetostriction of Grain Oriented 3%Si-Fe in the Magnetization Process.

抄録

Acoustic noise from power transformers is thought to be produced at the corners of their laminated cores, because the direction of the magnetization vector is not parallel to its [001] axis. To make clear the reason for this problem, we investigated magnetostriction in the magnetization process for grain-oriented silicon steels when the longitudinal direction of sample deviated from [001]. It was found that large contraction or expansion occurred as a result of magnetostriction, even if the deviation angle was small. This behavior was explained as due to reordering of the magnetic domain structure.
