The microstructure of hot-rolled and annealed samples was studied by OM. Experimental results indicate that a strong heredity is observed in texture evolution between hot-rolled texture and annealed texture. Typical elements have a large effect on the recrystallization microstructure and texture distribution. The texture distribution through thickness is highly affected by recrystallization in hot rolled sheets. The recrystallization is boosted by Si and Al. Goss grains originate from cracked initial columnar grains. {110} , {112} and {111} grains are related to Goss grains. In subsurface lay of hot rolled sheets, Al can strengthen Goss texture and weaken copper-type texture. {112} texture and {110} texture are strengthened by Si. In the central layers, {100} texture and {111} texture are weakened by Al. {100} texture is increased by Al. Si can increase the proportion of AaAaAeAA[sup.3]-fiber texture and decrease that of {100} texture and Goss texture are decreased by Al and Si. AaAaAeAA[sup.3]-fiber texture is increased by Si and {111} Author Affiliation: (1) Institute of Engineering Technology, University of Science and Technology Beijing, Beijing, 100083, China (2) Collaborative Innovation Center of Steel Technology, University of Science and Technology Beijing, Beijing, 100083, China Article History: Registration Date: 09/12/2017 Received Date: 12/08/2016 Accepted Date: 20/11/2016 Online Date: 14/12/2017 Article note: Funded by the Fundamental Research Funds for the Central Universities(TP-A3)( No.: FRF-TP-15-063A3)
