Effect of Texture Components on the Lankford Parameters in Ferritic Stainless Steel Sheets

Two ferritic stainless steel (FSS) sheets were produced to display different recrystallization textures. The in-plane variation of the Lankford parameter R(alpha) was calculated from the sheet textures and compared to the R-values determined experimentally. The textures of the FSS sheets were further decomposed into a number of individual texture components to clarify the effect of the main texture constituents on R(alpha). The in-plane variation of R(alpha) is mainly governed by the main texture component, while minor texture components generally reduce the overall level of R(alpha). A desirable high normal anisotropy (R) over bar and small in-plane variations of R(alpha) are obtained for texture components with an Euler angle Phi lying in the range 50 degrees <= Phi <= 60 degrees, which comprise the gamma-fiber orientations close to {111}//ND.
