摘要：

Tensile tests were performed for Zn at room temperature, which show elongations of 110%-20% for average grain sizes of 240-23 nm, respectively. The ductility of ultrafine-grained and nanocrystalline Zn was found to decrease with grain size refinement. The deformation mechanisms in ultrafine-grained Zn are believed to be a mixture of grain boundary sliding of small nanograins and intra-grain dislocation creep within the large grains.
