Quantification of Ridging in Ferritic Stainless Steel Sheets by Electron Backscattered Diffraction R-Value Maps
Published online by Cambridge University Press: 06 August 2013
Abstract
In ferritic stainless steel (FSS), undesirable surface defects of ridging appear during deep drawing. The formation of these defects is attributed to the inhomogeneous distribution of orientations of individual grains. In the present work, a new electron backscattered diffraction R(α)-value map was introduced, and the dependence of the tensile directions on the formation of ridging in an FSS sheet was discussed using this map. The results showed that large grain colonies in the R(α)-value maps lead to the formation of severe ridging in an FSS sheet.
