Abstract:Hot deformation behavior of high grade non-oriented silicon steel is investigated by Gleeble testing machine. The results show that grain recovery only has finished when temperature increases from 850 ℃ to 1150 ℃ in the test. Grain is the shape of the string when strain rate is low. Grain is the shape of their regularpolygon when strain rate is high.
