中文摘要	in this study, compositional dependence of age hardening response and tensile properties were investigated for mg-10g(d-x)y-0.4zr (x = 1, 3, 5 wt.%) alloys. with increasing y content, the age hardening response of the alloys enhanced and tensile properties increased. the mg-10gd-5y-0.4zr alloy exhibited maximum tensile strength and yield strength at aged-peak hardness, and the values were 302 mpa and 289 mpa at room temperature, and 340 mpa and 267 mpa at 250 degrees c, respectively. the strong peak age hardening was attributed to the precipitation of prismatic beta' plates in a triangular arrangement. the cubic shaped beta phase was also observed at grain boundaries. the remarkable improvement in strength is associated with a uniform and high dense distribution of beta' and cubic shaped beta precipitate phases in mg matrix. elongation of mg-10gd-0.4zr alloys decreased with increasing y content, and the elongation of mg-10gd-5y-0.4zr alloy was less than 3% below 250 degrees c, whereas the alloys containing i wt.% and 3 wt.% y exhibited higher elongation than 5% at room temperature.
