Title
Effect of Heat Treatment on Magnetic Properties of Solidified High Si - Fe Sheet Rapidly
구자명Jar Myung Koo, 조성석Seong Seock Cho
Abstract
The magnetic properties and the grain structure of 6.5 wt%Si-Fe alloy made by the twin roller method were measured after the various annealing temperature. When the annealing temperature was around 700℃, the primary recrystallization was formed near the middle part of the sheet thickness and the grain size increased with increasing temperature. When the sheets were annealed at 1200℃, the grains with the (100) planes were paralled to the sheet surface, The magnetic properties are improved by furnace cooling after annealing at 1200℃ for 1hr at the air pressure of 10^(-4) Torr.
