摘要

In this work, polycrystalline zinc samples were prepared and the activation of slip systems of polycrystalline zinc was studied by slip trace analysis. The average grain size of the polycrystalline zinc was 12.3 μm, the yield strength and fracture elongation were 132.6 ± 1.1 MPa and 76.9 ± 1.5%. The activities of a diverse range of slip systems and twinning patterns were suitably assessed by slip trace analysis and Schmid’s law. The basal slip was the primary mechanism of slipping because the critical resolved shear stress needed to activate the basal slip system is one order of magnitude smaller than that of the non-basal slip system. The basal slip system of pure zinc was activated when the Schmid factor surpassed 0.3. This study also presented an efficient approach that combines the Schmid factor and texture analysis to predict the activation type of slip systems.
