Strain Localization Behavior of Cold-Rolled Deep-Drawing Steels

Öz:
With the purpose of defining optimal microstructure and texture for higher quality in deep–drawingoperations of cold-rolled steels; this study monitors and analyses the micro- and macro-scale deformationbehavior of DC04 grade cold-rolled steel sheets under uniaxial tension and biaxial stretching. An in-planebiaxial test setup capable of observing and measuring the deformation is utilized for obtaining strain mapsat the micro- and macro-scale. Strain maps at the micro-scale are then compared with texture andmicrostructure data obtained before and after the deformation. Results show strain localization to theinterior of grains under both strain paths, as opposed to the common grain boundary localization observedin the literature. Remnants of the α fiber components in the initial γ fiber texture, especially grains with{100}<110> orientations, are the likely sources of the localizations as they allow deformation in the sheetthickness direction. While these localizations do not appear to be critical for macro-scale formability, theirsuppression should be helpful in preventing surface defects and local fracture. Total elimination of α fibercomponents from the initial texture is proposed as a way preventing micro-scale localizations.
