In the packaging industry, double-reduced (DR) tin
plate materials are produced by the deep drawing process and
are mostly used in the production of twist-off cap. However, one
of the most common problems in the deep drawing process is the
earing. This problem increases the cost of scrap cutting and
therefore decreases the production efficiency. In this study,
texture analysis were carried out by using electron backscatter
diffraction (EBSD) technique to clarify formation of earing. The
earing test, optic microscope (OM) examination and EBSD
technique were performed to material, which has same chemical
composition but three different thicknesses (0.14 mm, 0.17 mm
and 0.19 mm) in order to characterize the earing behavior. It was
determined that the earing value decreased with the increase in
thickness. In addition, it was confirmed that the earing were
related to <111> // ND fiber intensity, gamma (γ) fiber
distribution and grain size.
