Texture, Yield Locus and Plastic Anisotropy in Steel Sheets

Abstract

A comprehensive analysis of texture in the commercially produced low carbon aluminium-killed steel sheets of different thicknesses, by orientation distribution functions (ODF) technique, has been carried out. To characterise the plastic anisotropy behaviour of these sheets, studies about the evolution of Lankford parameter and yield locus prediction are performed, on the basis of Taylor theory using the {hkl} pencil glide {112} glide and {110} glide. The predicted r-values in the sheet plane are compared with the experimentally determined r-values.
