Strain Distribution Analysis Using Precise Markers in Cold-Rolled Ultra-Low Carbon Steel

In this study, the strain distribution in grains with a preferred orientation cold-rolled steel plate was investigated. This done by measuring amount of region material using nanoscale fine markers applied focused ion beam (FIB). We obtained crystal orientations and distributions same scanning electron microscopy-electron backscatter diffraction made FIB during rolling to 60% 70% thickness reduction. The method revealed major (cube:{100}<001>; α-fiber:{100}<011>, {211}<011>; γ-fiber:{111}<011>, {111}<211>). average strains that accumulated different cold-rolling were almost at reduction range 60%–70%. However, width γ-fiber approximately twice other orientations. These results suggest deformation inhomogeneity is more pronounced for γ-fiber-oriented than
