Abstract:

Effects of temper rolling on the cubic texture formation in primary recrystallized electrical steel were investigated. The results show that the cubic texture with columnar structure is obtained in the Fe-3.2%Si electrical steels through temper rolling and final annealing of primary recystallized sheets. In the formation of columnar structure, ∑5 and ∑11 grain boundaries decrease and finally disappear. This is beneficial to the growth of (100)［001］ grains. The migration of those grain boundaries is due to the special misorientation of 36.9°/〈100〉and 50.5°/〈110〉between (100)［001］ grains and primaries and the beneficial annealing environment.
