Abstract: The objective of the present study was to investigate the cold deformation texture and annealing texture in pure Zinc (Zn). As-cast pure Zn was subjected to cryo-rolling of 90% reduction in thickness followed by annealing at 50o C for different soaking times of 5 min, 10 min, 20 min and 30 min respectively. The texture and microstructure evolution during cryorolling and subsequent annealing of these samples were characterized through X-ray diffraction (XRD) and electron backscattered diffraction (EBSD). A dominant 1120 fiber texture was observed in both the rolled and annealed samples. However, the texture intensity was increased till 10 min of soaking time and it was then decreased on further increasing the soaking time. Only {1012} type tensile twins were observed in the samples and these twinning was found to be significant in all the samples. The Vickers hardness of the samples was increased till 10 min of annealing time followed by a decrease in hardness on further increasing the soaking time of annealing.
