Abstract A new high strength Mg sheet alloy, Mg-(3.0—3.8)%Zn-(0.6—1.0)%Y-(0.4—0.7)%Zr, has been developed. The final heat treatment condition is T_8 condition, namely, 515—520℃ solution treated 1h, water quenched+15% cold work+200℃ 24h. Its room temperature tensile properties are shown as: σ_b=33.5—34.0 or 29.0—30.0 kgf/mm~2; σ_(0.2)=30.0—30.5 or 19.5—20kgf/mm~2; δ=12—14 or 13.5—22.0% in longitudinal or transverse direction respectively. And its tensile properties below 250℃ are superior to that of both HM21XA-T_8 and AZ31B-H_(24).
