Abstract :
The effect of cooling rate on order degree of 6.5 wt% Si electrical steel using various cooling rate was investigated. The results show that with an increasing of the cooling rate, the order degree decreases, and the morphology of B2 ordered phase transforms from island-like to punctate, but for the DO3 is still punctate until it dispersed. The B2 ordered phase is almost impossible to be suppressed completely, but the DO3 ordered phase can be suppressed completely when the cooling rate is greater than or equal to water quenching cooling rate. For the liquid nitrogen quenching, the average size of the B2 ordered domain is greater than that of the water quenched.
