摘要：Simultaneous improvements in strength and corrosion resistance of Mg-Gd-Y-Zr alloy were realized through forging at room temperature with formation of ultrafine grained (UFG) structure. Compared with its coarse grained (CG) counterpart, the UFG sample exhibits an enhancement of 211 MPa (103%) in yield strength and a reduction of 0.644 x 10 (5) A/cm(2) (25%) in corrosion current density. Effect of microstructure on the mechanical property was quantitatively investigated, revealing a good coincidence of the experimental result with the calculated one based on Bailey-Hirsch equation. The improvement in corrosion resistance is attributed to the formation of sub-grain boundaries.
