The objective of this work is to investigate a method by which high silicon alloys containing up to 6.5% Si can be process by rolling applying hot-cold working techniques. Alloys with 4.5 and 6.3%Si were cast, hot and cold rolled using an adequate scheme. A final thickness of 1mm after hot rolling and of 0.5 mm after cold rolling was obtained. After hot rolling a heterogeneous microstructure is observed over the sheet thickness: shear bands in the surface and a central zone with elongated grains. The recrystallization is strongly retarded at lower temperature and specifically in the high-Si steel because of ordering. The microstructure of the cold rolled material is similar to the hot rolled microstructure, due to the lack of recrystallization. After annealing for 2 hours at 900°C secondary recrystallization is observed and texture is weakened.
