Abstract Scope |
For Non-Oriented grades of electrical steel the <001>//ND texture provides the best prospect for optimising the magnetic properties. However, after conventional cold rolling and annealing the <111>//ND texture appears, which is precisely opposite of what is necessary. One alternative to conventional cold rolling is warm rolling. Recrystallization after warm rolling enhances the <001> fibre texture. In this paper the recovered structure just before the onset of primary recrystallization is analysed in detail on an interstitial free (IF) steel, to be regarded as a model material for ultra-low-carbon steels, including electrical steels. A difference is observed between the dynamically recovered structure after warm rolling to a reduction of 80% at 550°C and after static recovery at 500°C of a cold rolled sheet rolled to a reduction of 75%. It will be explained how such subtle structural differences are of crucial importance for texture formation during primary recrystallization. |
