Abstract：The high temperature microstructure of grain oriented silicon steel at 850-1300℃ has been studied by using optical microscope and scanning electron microscope. The influences of alloy elements and temperature on austenite volume fraction, and the distribution of alloy elements in austenite and ferrite have been investigated. The results show that the temperature range for high temperature microstructure with maximum volume fraction of austenite phase in the grain oriented silicon steel of different chemical compositions is about 1100-1200℃, and the temperature for the maximum volume fraction of austenite phase increases with increase of the content of austenite-stabilizing elements. There is a linear relationship between the carbon content and austenite volume fraction in grain oriented silicon steel at high temperature.
