Abstract
The microstructure and texture evolution of Fe-16%Cr ferritic stainless steel has been studied with the variation of annealing process. Interrelation between ridging phenomenon and microtexture was investigated. The annealing process was conducted in 4 different types, such as B-C, B-B, C-C and C-B. (B: batch annealing, C: continuous annealing) in both hot band and cold rolled steels. The rolling and recrystallization textures at each process were examined by orientation distribution function(ODF). In order to investigate the orientation of each grain and the existence of grain colonies, microtexture measurements were performed with electron back-scatter diffraction(EBSD) on the TD section. The ridging behavior was surveyed after 15% tensile elongation. It was found that the ridging property was improved remarkably in C-B annealing process due to the disintegration of coarse colonies after full recrystallization. It was clearly found that the ridging phenomenon was closely related with the existence of grain clusters or grain colonies having the {001}$lt;110$gt; orientation.
