Abstract: Bulk ultra fine grained (UFG) Zn was produced by in situ consolidation of Zn elemental powder with ball milling at room temperature and annealed for 1 hour at 200 after pure Zn milled. The 150 % elongation is obtained in UFG Zn during tensile test at 20 which is equal to 0.43 Tm (Tm is the melting temperature of pure Zn). The elongation of UFG Zn is higher than the 110 % elongation of nanocrystalline Zn ball milled at tensile elongation. The largest tensile elongation (150%) was observed at room temperature in UFG Zn.
