Three–point bending tests were performed on pure zinc single crystals with different crystal orientations to investigate orientation dependence on bending
deformation behavior. With basal planes parallel to the neutral planes, the specimens deformed due to basal slips and formed a gull–shape after deformation. On
the other hand, the specimen whose neutral planes are perpendicular to basal planes and neutral axes are perpendicular to [0001] deformed due to second order
pyramidal <c + a> slips, f1012 g twinning and basal slips within f1012 g twins, displaying a V–shape. Bending deformation behavior of pure zinc single crystals
was found to show strong orientation dependence. Also, bending deformation behavior of pure zinc single crystals was found to differ from that of pure magnesium
single crystals when the neutral plane and neutral axis are respectively perpendicular to basal planes and
